Hereinafter, the terahertz wave generator 1 according to the present invention will be described with reference to FIGS. 1 to 8.

Figure 1 shows the external appearance of the terahertz wave generator 1 with the upper cover removed according to an embodiment of the present invention. Figure 2 shows the external appearance of a terahertz wave generator 1 with an upper cover according to an embodiment of the present invention.

Referring to Figures 1 and 2, the terahertz wave generator 1 according to the present invention includes a case 400, a light source module 200, a support part 100, and a light alignment part 300.

The support unit 100 may serve to support the light source module 200. In detail, it may include a plurality of frames 130 supporting the light source module 200 and mounts 110 and 120 supporting the frames 130.

At least two mounts 110 and 120 may be arranged to maintain the balance of the frame 130. Referring to the embodiment of FIG. 1, the first mount 110 and the second mount 120 may be fitted and coupled to support both ends of the frame 130.

The frame 130 may be supported by connecting the light source module 200. In detail, the frame can be inserted into and supported in the holes arranged at the four corners of the light source module 200. By maintaining the balance of the frame 130, movement of the light source module 200 can be prevented. The coupling structure will be described in more detail with reference to FIG. 3.

The light source module 200 includes a mirror 210, a mirror housing 220, and an aperture 230. The light source module 200 can generate terahertz waves through a laser irradiated from an external light source. The laser irradiated from the external light source may be a femto-second laser. Femtosecond laser refers to a laser with a very short pulse width of 10 ^-15 seconds. Since the terahertz wave generator 1 according to the present invention does not include a light source, various light sources can be selected and used.

The mirror 210 can optically align the terahertz waves generated while passing through the aperture 230. In more detail, the mirror 210 may serve to align the direction of terahertz waves generated through the aperture 230. The nonlinear crystal 231 disposed inside the aperture 230 can convert a femtosecond laser into a terahertz wave. However, due to the nonlinear nature of the crystal 231, the generated terahertz wave may proceed in an irregular direction. Therefore, in order to smoothly use terahertz waves for the purpose, the mirror 210 may be included in the light source module 200. The specific shape of the mirror 210 and the method of aligning the direction of the terahertz wave will be described later with reference to FIG. 8.

The mirror housing 220 may support the mirror 210 by providing a space in which the mirror 210 is placed. The mirror housing 220 may be connected to the tilting device 330 on the other side where the mirror 210 is disposed. The detailed coupling structure will be described later with reference to FIG. 5.

The aperture 230 has a crystal 231 disposed inside it, and can convert laser irradiated from an external light source into terahertz waves and output them. The external light source can be selected with various specifications, and it is necessary to adjust the angle of the crystal 231 to increase the output efficiency of terahertz waves. Accordingly, the aperture 230 may be configured to be detachable so that the angle of the crystal 231 can be adjusted. Additionally, the aperture 230 is configured as a rotatable dial, so that the user can adjust the angle of the crystal 231 by rotating it according to an external light source.

Unlike conventional terahertz wave generation means, the nonlinear crystal 231 can transform a laser into a terahertz wave by its shape characteristics without any power supply. Therefore, there is no need to connect an external power source, providing the effect of miniaturizing the size of the terahertz wave generator.

The light source module 200 needs to have its axes arranged on the same line in order to perform the function of converting the laser irradiated in a straight line through the light source into terahertz waves. More specifically, the light source, aperture 230, and mirror 210 may be arranged on the same axis.

The optical alignment unit 300 may include a base 310, a positioning lobe 320, and a tilting device 330. The optical alignment unit 300 is connected to the light source module 200, and can adjust the position of the light source module 200 for optical alignment of terahertz waves.

The base 310 may have a light source module 200 including a mirror 210 and a support portion 100 disposed thereon. The base 310 is formed of flat plates forming a plurality of stages so that the height can be adjusted. The user can adjust the height of the base 310 to adjust the height of the mirror 210 and the aperture 230 and place them on the same axis as the light source.

The position control lobe 320 is coupled to the base 310 and can adjust the position of the base 310. The user can adjust the height of the base 310 by manipulating the position adjustment lobe 320, which will be described later with reference to FIG. 4.

The tilting device 330 is connected to the mirror housing 220 and can adjust the angle of the mirror 210. According to this embodiment, the tilting device 330 includes three tilting knobs 331, 332, and 333, allowing the operator to adjust the angle of the mirror in three axes xyz. The combined structure of the mirror housing 220 and the tilting device 330 will be described later with reference to FIG. 5.

Referring to FIG. 2, the case 400 includes an upper cover 410 and a bottom plate 420. The upper cover 410 may be combined with the bottom plate 420 to form an internal space. A support unit 100, a light source module 200, and a light alignment unit 300 may be disposed in the internal space. The user can place the support part 100, the light source module 200, and the light alignment part 300 on the top of the bottom plate 420, and then couple the upper cover 410 to the bottom plate 420. Accordingly, the optically aligned light source module 200 and the optical alignment unit 300 can be protected from external stimulation or interference.

The upper cover 410 may include an entrance hole 411 and an output hole 412. The entrance hole 411 may be formed on one side of the upper cover 410 so that the laser irradiated from an external light source can enter the internal space.

Accordingly, the laser incident on the internal space may be directly incident on the aperture 230. The entrance hole 411 may be circular in shape.

The output hole 412 may be disposed on the side of the upper cover 210 so that the terahertz waves generated by the aperture 230 are reflected by the mirror 210, aligned, and then output to the outside. Considering the direction of travel of the terahertz wave reflected by the mirror 210, the incident hole 411 and the output hole 412 may be respectively disposed on both vertical sides of the upper cover 210.

The bottom plate 420 has a support portion 100, a light source module 200, and a light alignment portion 300 disposed on the top.

Figure 3 shows a coupling structure of the light source module 200 and the support part 100 according to an embodiment of the present invention.

Referring to the embodiment of FIG. 3, the first mount 110 and the second mount 120 may be connected to both ends of the plurality of frames 130, respectively.

The mirror 210 may be coupled to one surface of the mirror housing 220, and the mirror housing 220 may be coupled to the tilting device 330. The tilting device 330 may be formed with a plurality of arms 334 and 335. The arms 334 and 335 of the tilting device 330 may be formed with open ends so that the frame 130 can be inserted. The detailed shapes of the arms 334 and 335 will be described later with reference to FIG. 5 .

The aperture 230 is inserted into and fixed to the frame 130. More specifically, the frame 130 may pass through and be fixed to a plurality of holes formed in the aperture 230. The first mount 110 may be fitted into the frame 130 after the aperture 230 is fitted and coupled to the frame 130 . The frame 130 can be prevented from moving by the first mount 110 and the second mount 120. The first mount 110 and the second mount 120 may include a coupling portion extending from the lower portion so as to be fixed to the base 310 . The coupling portion is formed to include a plurality of holes and can be bolted together with the holes existing in the base 310.

Figure 4 shows the coupling structure of the base 310 and the positioning lobe 320 according to an embodiment of the present invention.

Referring to FIG. 4, the base 310 may be formed by forming a plurality of blocks. A plurality of blocks may be connected to each other with penetrating internal supports (not shown).

The position control lobe 320 is connected to the base 310 and can adjust the height and position of the base 310. More specifically, one position control lobe arranged in the vertical direction and one position control lobe arranged in the horizontal direction may be connected to the base 310.

The uppermost end of the base 310 may be movable in a vertical direction. The internal support is raised by the positioning lobe 320 arranged in the vertical direction, and the uppermost end of the base 310 can be raised. Additionally, one end of the base 310 can move in the horizontal direction. The user can move the base 310 by manipulating the position control lobe 320 arranged in the horizontal direction. Therefore, the position of the base 310 can be adjusted up and down by the user to increase terahertz wave generation efficiency and align the light.

The bottom of the base 310 can be fixed by combining with the bottom plate 420. Accordingly, the movement of the base 310 is limited to the remaining stages excluding the lowest stage among the plurality of stages.

A plurality of holes may be formed at the top of the base 310. It is formed to correspond to the hole existing in the mounts 110 and 120 of the support part 100 disposed at the top, and can be fixedly coupled with bolts at the same time.

Figure 5 shows the combined structure of the mirror 210, the mirror housing 220, and the tilting device 330 according to an embodiment of the present invention.

The mirror housing 220 to which the mirror 210 is coupled is coupled to the tilting device 330. The tilting device 330 may include three tilting knobs 331, 332, and 333. The three tilting knobs 331, 332, and 333 can adjust the angle of the mirror 210 in the X, Y, and Z axis directions, respectively. Therefore, the user can adjust the angle of the mirror 210 to align the terahertz waves and output them to the outside through the output hole 412.

The tilting device 330 may include a plurality of arms 334 and 335 whose ends are opened so that the frame 130 can be inserted.

The upper arm 334 may have a streamlined groove formed at an end corresponding to the frame 130. When combined, flow across the frame 130 can be prevented.

The lower arm 335 may be narrowed from the end and may be formed in the shape of a tong with a circular space formed inside to correspond to the shape of the frame 130. The user can insert the frame 130 into the lower arm 335 by pressing it above a certain level. The frame 130 may be placed in the inner space of the lower arm 335 and then fixed by the narrowing shape of the lower arm 335 when the user's pressure is stopped.

FIG. 6 shows the structure of the aperture 230 according to an embodiment of the present invention, and FIG. 7 shows the shape of a crystal included within the aperture 230 according to an embodiment of the present invention.

The aperture 230 includes a crystal 231 therein. The aperture 230 is formed to be disassembled and can be combined after placing the crystal 231 therein. The aperture 230 may be formed in the shape of a dial so that the angle of the crystal 231 can be adjusted without separating the coupled aperture 230 again. Therefore, the user can adjust the angle by rotating the dial without removing the aperture 230 fixed to the frame 130 again.

The crystal 231 serves to transform the femtosecond laser into terahertz waves. Even if a separate power source is not connected, terahertz waves can be generated due to the shape characteristics. Since it is non-linear and terahertz waves can be scattered, optical alignment is required, and terahertz waves can be aligned through the mirror 210.

Figure 8 shows a structure in which a mirror 210 according to an embodiment of the present invention optically aligns terahertz waves.

As described above, the terahertz wave (W) generated by the nonlinear crystal 231 may be scattered by the irregular shape of the crystal 231. Therefore, referring to FIG. 8, in this embodiment, the angle can be aligned by reflecting the terahertz wave (W) to the mirror 210.

The mirror 210 may be made of a concave mirror and may be formed in a concave shape at the center. Terahertz waves (W) reflected from the mirror 210 are output aligned at the same angle.

Assemble the aperture 230 by fixing the rearranged crystal 231. (S135) After inserting the assembled aperture 230 into the frame 130, the first mount 110 is coupled and fixed.

After the rearrangement of the aperture 230 is completed, the femtosecond laser is irradiated to the aperture 230 again through an external light source. (S131)

However, if the aperture 230 is designed in a dial format to be rotatable, the occurrence of terahertz waves can be checked by rotating the dial before disassembling the aperture (S133). (not shown)

Referring to FIG. 11, after the end of the terahertz wave generation step (S130), a light source module (including a mirror 210) is installed so that the terahertz wave generated through the aperture 230 can be reflected through the mirror 210. 200) position can be adjusted. (S141)

In more detail, the light source module position setting step (S141) may adjust the height of the base 310 so that the terahertz wave generated in the terahertz wave generation step (S130) can be irradiated to the mirror 210. (S141a, not shown)

After the exit of the mirror tilting step S142, the user places the upper cover 410 on the top of the support portion 100, the light source module 200 and the light portion 300, and then through the output hole 412 Check whether Hertz waves are output. (S143)

When the output of the terahertz wave is confirmed in the terahertz wave output confirmation step (S143), the optical alignment step (S140) is completed, and the device fixing step (S150) for fixing the disposed upper cover 410 is started.

If the terahertz wave is not output in the terahertz wave output confirmation step (S143), the case 400, specifically the upper cover 410, is separated from the bottom plate 420 again. (S144)

After the case separation step (S144), the light source module position setting step (S141) can be started again. In particular, by re-performing the mirror tilting step (S142), the output direction of the terahertz wave can be re-adjusted.
