Laser aid also includes being placed on the first Multiplexing apparatus 104a in the second laser beam 121b light path and the second Multiplexing apparatus 104c.Fig. 1 C is the view that laser aid looks in face of emergent light direction.Being divided into two parts, Part I to be incident in first Multiplexing apparatus 104a transmission (in fig. 1 c on above-below direction) with reference to Figure 1A and Fig. 1 C, the second laser beam 121b on its major cross-sectional axis direction, Part II is incident in the second Multiplexing apparatus 104c transmission.Wherein, first laser beam 121a is also incident in the first Multiplexing apparatus 104a, first Multiplexing apparatus 104a reflects the first laser beam 121a and is combined into a branch of by the Part I of the first laser beam and the second laser beam, and after conjunction light, the major cross-sectional axis direction of the first laser beam 121a is orthogonal with the major cross-sectional axis direction of the second laser beam 121b；3rd laser beam 121c is incident in the second Multiplexing apparatus 104c, the Part II of the 3rd laser beam and the second laser beam is also combined into a branch of by the second Multiplexing apparatus reflection the 3rd laser beam 121c, and after conjunction light, the major cross-sectional axis direction of the 3rd laser beam 121c is orthogonal with the major cross-sectional axis direction of the second laser beam 121b.
In the present embodiment, the second laser beam 121b is divided into two parts along long axis direction, the conjunction light that these two parts of light beams are orthogonal with the first laser beam 121a and the 3rd laser beam 121c cross section respectively.Owing to the cross section of each laser beam width on long axis direction is not less than being orthogonal to two times of width on long axis direction, total light beam after the conjunction light so formed is at diametrically not increase (the dotted line 102b in reference to Fig. 1 C) of cross sectional shape, and laser power enhances three times simultaneously.
In the present embodiment, the first lasing light emitter 101a, the second lasing light emitter 101b and the 3rd lasing light emitter 101c launch laser beam towards equidirectional.Simultaneously, laser aid also includes the first reflecting mirror 103a and the second reflecting mirror 103c, first reflecting mirror 103a makes it be incident in the first Multiplexing apparatus 104a for reflection the first laser beam 121a, second reflecting mirror 103c makes it be incident in the second Multiplexing apparatus 104c for reflection the 3rd laser beam 121c, and what the solid arrow in Fig. 1 C represented is the light of reflection.Such it is advantageous in that system design comparison is succinct；And, laser can be conveniently mounted at same cooling base, and it is low that system installs complexity.
In the present embodiment, also include three collimating lens 102a, 102b and 102c, for the laser alignment sent by lasing light emitter.In Fig. 1 C, dotted line 102a, 102b and 102c are exactly the projection of these three collimating lens.
In the present embodiment, Multiplexing apparatus (including the first Multiplexing apparatus and the second Multiplexing apparatus) reflects respectively and two incoming laser beams of transmission are a branch of they to be combined into.Two incoming laser beams are reflected and transmission respectively, it is desirable to the two light beam is different on some attribute, and Multiplexing apparatus utilizes this difference to make a distinction two light beams exactly.Such as, the wavelength of two incoming laser beams is different, and Multiplexing apparatus just can use light splitting optical filtering sheet film to realize, and i.e. to the laser beam transmission of a wavelength, laser beam to another wavelength reflects (the different conjunction light i.e. utilizing wavelength) simultaneously.The most such as, two incoming laser beams have mutually orthogonal polarization direction, now Multiplexing apparatus just can use reflective polarizing light splitting sheet film to realize, i.e. the incoming laser beam of orthogonal polarization direction is reflected by the incoming laser beam transmission to a polarization direction simultaneously.Certainly, if the wavelength of two incoming laser beams and polarization direction are the most different, utilizing wavelength and polarization direction to close light so that close light more simply, direct effect is exactly that Multiplexing apparatus is prone to processing simultaneously.
In the present embodiment, the polarization direction of each laser beam (121a, 121b and 121c) is identical particular value with the angle angle of the long axis direction in its cross section, such as, be parallel to its long axis direction or be perpendicular to its long axis direction.Now, orthogonal due to the major cross-sectional axis direction of the first laser beam and the second laser beam, then its polarization direction is the most orthogonal, the first Multiplexing apparatus just can utilize the orthogonality of polarization direction that the Part I of the first laser beam and the second laser beam is closed light.As a same reason, the second Multiplexing apparatus can also utilize the orthogonality of polarization direction that the Part II of the 3rd laser beam and the second laser beam is closed light.Certainly, the first Multiplexing apparatus and the second Multiplexing apparatus can also utilize different method to close light, and such as one utilizes polarization direction just joining light, and another utilizes the different of wavelength to close light, and this obviously falls within protection scope of the present invention.
