Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of light coupling equipment and relates to a full-automatic FAC mirror collimation system. Background Art
[0002] Fiber-output high-power semiconductor lasers have been increasingly widely used as fiber laser pump sources and as direct light sources for industrial processing, and the power demand is constantly increasing. The collimated coupling structure of fiber-output high-power semiconductor lasers mainly solves two problems in increasing output power. One is to improve heat dissipation efficiency and reduce the temperature rise of the laser chip. The other is to achieve close beam arrangement to improve coupling efficiency and efficiently couple more single-tube semiconductor laser light into the specified optical fiber. In terms of improving heat dissipation efficiency, no matter what heat dissipation method is used, it is crucial to shorten the distance between the heat source and the heat dissipation surface. The so-called close beam arrangement means that when the same number of beams are arranged together without blocking the light, the circumscribed circle of the outermost point of the beam is the smallest, or the most beams are placed in a circle of the same diameter. If the spot of a single-tube semiconductor laser collimated beam is equivalent to a rectangle, when the collimated beams of multiple single-tube semiconductor lasers are combined, the long sides of the rectangles are close to each other and the short sides are aligned, which is called a regular arrangement. If the long sides of the rectangles are close to each other but the short sides are not aligned, it is called an oblique arrangement. For the same collimated beam, the circumscribed circle of the combined beam spot formed by the oblique arrangement will be larger than the circumscribed circle of the combined beam spot formed by the regular arrangement. Therefore, only a regular arrangement can achieve close packing of the beams.
[0003] The collimation and beam combining structure of multiple single-tube semiconductor lasers is composed of semiconductor laser single-chip collimation units through spatial beam combining, polarization beam combining or wavelength beam combining. Among them, the collimation beam combining array composed of a column of single-chip collimation units for spatial beam combining is the most basic structure. Further improvement of power can be achieved by spatial beam combining, polarization beam combining or wavelength beam combining of this collimation beam combining array. Since the spatial beam combining, polarization beam combining and wavelength beam combining technologies of the collimation beam combining array are relatively mature, it is very important to design the optimal collimation beam combining array structure. The basic unit in the collimation beam combining array is the single-chip collimation unit, so the structure of the collimation beam combining array is mainly reflected by the structure of the single-chip collimation unit. The single-chip collimation unit is mainly composed of components such as a heat sink, a laser chip assembly (COS), a fast axis collimation lens (FAC), a slow axis collimation lens (SAC) and a 45-degree reflector.
