Embodiment one:
in this embodiment, a terahertz optical wave amplifier as shown in fig. 1 to 6 includes a first amplifier housing 1, an end cover 2, and a plurality of amplifying units 3; the end of the first amplifier housing 1, which is far away from the end cover 2, is provided with a waveguide mounting hole 11; the radius of the first amplifier housing 1 gradually increases from the waveguide mounting hole 11 to the end cap 2; the end cover 2 is positioned on the side wall of the inner cavity of the first amplifier shell 1 and is uniformly provided with a plurality of amplifying units 3; a plurality of scattering chips 4 are arranged on the side walls of the amplifying unit 3, which are close to and far from the end cover 2, and a scattering coating 5 is arranged on the scattering chips 4; the inner cavity surface of the first amplifier housing 1 is covered with a reflective coating; the radiation end of the waveguide tube in the waveguide tube mounting hole 11 is aligned with any amplifying unit 3, and the other end of the waveguide tube is connected with a terahertz light wave instrument. The terahertz light wave instrument is emitted by the waveguide tube and is led into the first amplifier shell 1, meanwhile, as the emitting end of the waveguide tube is aligned with the amplifying unit 3, the terahertz light wave is directly emitted to the amplifying unit 3, and then the terahertz light wave is scattered by the scattering coating 5 on the surface of the scattering chip 4, so that the output range of the output terahertz light wave is larger; meanwhile, the scattering coating 5 can reflect part of the terahertz light waves to the surface of the inner cavity of the first amplifier shell 1, and the reflection coating of the inner cavity of the first amplifier shell 1 reflects the received terahertz light waves again, so that energy loss in the scattering process is reduced. The invention can enlarge the output range of the terahertz light wave without increasing the power of the terahertz light wave emission source.
In this embodiment, as shown in fig. 5, the scattering chip 4 is a circular sheet, the scattering coating 5 is provided with a plurality of arc segments along the radial direction of the scattering chip 4, and adjacent arc segments along the radial direction of the scattering chip 4 have gaps and are connected by straight segments; gaps are reserved between adjacent arc-shaped sections on the same circumference of the scattering chip 4; the gaps between the arc segments of the scattering coating 5 provide room for the scattering of terahertz light waves.
In this embodiment, the reflective coating and the scattering coating 5 are both silver-nickel alloy materials.
In this embodiment, the amplifying unit 3 is a fan, and the amplifying unit 3 can drive the scattering chips 4 at two sides of the amplifying unit to rotate, so that the scattering angle of the scattering chips 4 can be larger when the fan rotates.
The invention can also be used as an amplifying device for microwaves or ultrasonic waves.
In this embodiment, the end of the waveguide far away from the waveguide mounting hole 11 may be connected to a microwave generator or an ultrasonic generator, and the silver-nickel alloy reflective coating and the scattering coating 5 can also reflect and scatter microwaves and ultrasonic waves. Namely, the terahertz optical wave amplifier in the present embodiment can be used as a microwave amplifier and an ultrasonic amplifier as well.
Embodiment two:
the difference between this embodiment and the first embodiment is that:
the reflection coating of the waveguide tube in the catheter mounting hole 11 aligned with the first amplifier housing 1, instead of the amplifying unit 3, directly uses the reflection coating of the inner cavity of the first amplifier housing 1 to scatter the terahertz light waves.
Embodiment III:
the difference between this embodiment and the first embodiment is that:
the diffusion chip 4 is directly disposed on the side wall of the end cover 2 close to the first amplifier housing 1 instead of being mounted on the amplifying unit 3, i.e., in this embodiment, the amplifying unit is not disposed inside the first amplifier housing 1, and the diffusion chip 4 is directly adhered to the inner side of the end cover 2.
Embodiment four:
the embodiment provides another alternative for the specific structure of the terahertz optical wave amplifier on the basis of any embodiment.
In this embodiment, as shown in fig. 7 and 8, the terahertz optical wave amplifier in this embodiment includes a second amplifier housing 6, a cavity is formed inside the second amplifier housing 6, a terahertz optical wave generating device 7 is disposed in an inner cavity of the second amplifier housing 6, a plurality of scattering windows 61 are uniformly disposed on a side wall of the second amplifier housing 6, a power line reserved hole 62 is formed on a top wall of the second amplifier housing 6, a power interface 71 is disposed at a top of the terahertz optical wave generating device 7, and terahertz optical waves can be generated after the terahertz optical wave generating device 7 is powered on. The inner wall of the second amplifier housing 6 is made of silver-nickel alloy, and the terahertz light wave emitting port of the terahertz light wave generating device 7 is aligned with the side wall of the inner cavity of the second amplifier housing 6 and staggered with the scattering window 61.
Alternatively, the cross-sectional area of the second amplifier housing 6 is a combined shape of an arc and a line segment, an ellipse, a circle, or a polygon.
In the present embodiment, the cross-sectional area of the second amplifier housing 6 is circular, i.e., the second amplifier housing 6 is a cylindrical housing.
In other embodiments, the second amplifier housing 6 is a square housing.
In other embodiments, the second amplifier housing 6 is an oval housing.
In other embodiments, the second amplifier housing 6 is a semi-cylindrical housing.
When the terahertz light wave generating device 7 is powered on, terahertz light waves are generated, the terahertz light waves are repeatedly ejected on the side wall of the inner cavity of the second amplifier housing 6 made of silver-nickel alloy and then are emitted from the scattering window 61, and the emitting direction of the terahertz light waves is not limited to the emitting angle of the terahertz light wave emitting port of the terahertz light wave generating device 7 any more due to the fact that the terahertz light waves are repeatedly reflected in the inner cavity of the second amplifier housing 6, when the terahertz light waves are finally emitted out of the scattering window 61, the angle is uncertain, and the angles of the terahertz light waves reflected out of the scattering window 61 from the side wall of the inner cavity with different angles are different, so that the terahertz light waves have a larger irradiation range after being emitted out of the scattering window 61.
The terahertz light wave generating device 7 in this embodiment and the terahertz light wave meter in the first embodiment may be replaced with each other.
The second amplifier housing 6 in the present invention can also be used as an amplifying device for microwaves or ultrasound.
In this embodiment, the second amplifier housing 6 may be provided with a microwave generator or an ultrasonic generator instead of the terahertz light wave generating device 7, and the inner wall of the second amplifier housing 6 made of silver-nickel alloy can also reflect and scatter microwaves and ultrasonic waves.
