The working principle of the beam processing sub-apparatus 100 provided in the embodiment of the present disclosure will be specifically described below with reference to fig. 5, which mainly includes two processes of beam combining and beam splitting.
As shown in fig. 5, when the beam processing sub-apparatus 100 is used for multi-wavelength beam combination, the following processes are mainly involved:
wavelength of λ1The light beam is collimated by the first beam splitter collimator 201, then filtered by the first filtering component 401, and then enters the first transflective component 301 which is arranged at 45 degrees with the horizontal direction to be reflected, and then horizontally transmits the second transflective component 302, the third transflective component 303 and the fourth transflective component 304 in sequence, and finally is input to the main beam collimator 10.
Wavelength of λ2The light beam is collimated by the second beam splitter collimator 202, then filtered by the second filtering component 402, and then enters the second transflective component 302 disposed at 45 degrees to the horizontal direction to be reflected, and then horizontally transmits the third transflective component 303 and the fourth transflective component 304 in sequence, and finally enters the main beam collimator 10.
Wavelength of λ3The light beam is collimated by the third beam splitter collimator 203, then filtered by the third filtering component 403, and then enters the third transflective component 303 disposed at 45 degrees to the horizontal direction to be reflected, and then directly horizontally transmits the fourth transflective component 304, and finally enters the main beam collimator 10.
Wavelength of λ4The light beams are collimated by the fourth beam splitter collimator 204, filtered by the fourth filtering component 404, incident to the fourth transflective component 304 disposed at 45 ° to the horizontal direction, reflected, and then directly input to the main beam collimator 10 horizontally.
Wavelength of λ1Light beam of (2), wavelength is lambda2Light beam of (2), wavelength is lambda3Light beam and wavelength of lambda4The light beams are output to the main beam collimator 10 and then converged into a main beam, and then enter the optical fiber for output.
As shown in fig. 5, when the beam processing sub-apparatus 100 is used for splitting a multi-wavelength beam, the following processes are mainly involved:
from λ 1, λ2、λ3、λ4The main beam composed of the four different wavelengths is input to the main beam collimator 10 through the optical fiber, and is collimated by the main beam collimator 10 and then enters the fourth transflective assembly 304.
Wavelength lambda4The light beam is reflected by the fourth transflective assembly 304, filtered by the fourth filter assembly 404, and output to the fourth beam splitter 204.
Wavelength lambda3The light beam is transmitted by the fourth transflective assembly 304, then output to the third transflective assembly 303 for reflection, filtered by the third filtering assembly 403, output to the third beam splitter 203, and output.
Wavelength lambda2The light beams are transmitted by the fourth transflective assembly 304 and the third transflective assembly 303 in sequence, then output to the second transflective assembly 302 for reflection, filtered by the second filtering assembly 402, output to the second beam splitter 202, and output.
Wavelength lambda1The light beams are transmitted by the fourth transflective assembly 304, the third transflective assembly 303 and the second transflective assembly 302 in sequence, then output to the first transflective assembly 301 for reflection, filtered by the first filtering assembly 401, output to the first beam splitter collimator 201 and output.
As can be seen from the above embodiments, λ1、λ2、λ3、λ4The corresponding wavelength of the light beams with four different wavelengths is as follows: lambda [ alpha ]1＞λ2＞λ3＞λ4That is, the working wavelength corresponding to the first beam splitter 201, the first filter module 401 and the first transflective module 302 is the largest, and the working wavelength corresponding to the fourth beam splitter 204, the fourth filter module 404 and the fourth transflective module 304 is the smallest.It should be noted that the above embodiments show that the processing of the beam collimators differs from each other in the beam wavelength. In other embodiments, the wavelengths of the light beams processed by the partial beam collimators may be set to be the same according to actual requirements, and the beam collimators and the transflective assemblies corresponding to different wavelengths may be arranged according to requirements, which is not limited in this disclosure.
