Space beam combination device and system

Abstract

The invention discloses a space beam combination device and system. The space beam combination device comprises a laser array, a collimator and a reflection mirror array, wherein the laser array comprises N lasers, the reflection mirror array comprises N reflection mirrors corresponding to the N lasers, and N is a positive integer more than 1; laser beams emitted by each laser in the laser array are incident on the corresponding reflection mirror; the collimator is used for collimating each laser beam; each reflection mirror in the reflection mirror array is used for reflecting the incident laser beams and then outputting a laser beam array; the laser beam array comprises N mutually parallel and coplanar laser beams; and the optical distances from a light source to the output position of the laser beams are the same. The scheme has the beneficial effects that the principle is simple, parts are reasonably allocated, the implementability is strong, the adjustment difficulty is low, the flexibility is high, the number of the lasers in the laser array is easily increased, and thus space beam combination requirements are met.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a space beam combining device and system. Background technique [0002] Laser beam combining technology is a process of improving beam quality, increasing output power, and increasing power density. Common laser beam combining methods include spatial beam combining, polarization combining and wavelength combining. The application scenarios of spatial beam combining are as follows: [0003] A single semiconductor laser has the advantages of high efficiency, compact structure, low cost and high reliability, but the output power of a single semiconductor laser is low, and the beams of multiple semiconductor lasers are spatially combined to obtain high power. figure 1 A schematic diagram of a spatial beam combiner in the prior art is shown. Such as figure 1 As shown, the semiconductor laser tubes are placed on different steps on the stepped plate, and the laser beams emitted by each...
