Abstract

A multi-beam-hole splicing and synthesizing system based on the stable control of light beam directing comprises a multi-channel laser, a light-beam-expanding collimator, a plurality of titling mirrors, a plurality of reflecting mirrors, a base, a light beam synthesizing sensor, a light beam splitter, a control computer and a multi-channel tilting mirror amplifying power supply. According to the multi-beam-hole splicing and synthesizing system, the multi-channel light beam with high duty ratio is realized by utilizing the step-shaped base and the special-shaped design of the plurality of reflecting mirrors; and the light beam synthesizing sensor is used for detecting the vibration and the drifting of each light beam, and the plurality of titling mirrors are utilized for realizing the stable control of an optical axis of each light beam, so that the high-precision light beam synthesizing of the multi-channel light beam can be realized. The system can be used for the synthesizing emission of multiple paths of light beams and also can be sued for occasions such as the communication of multiple paths of laser. The system also can be used for moving platforms such as vehicles, ships, airplanes and the like as the dynamic random vibration and the drifting of each light beam can be controlled.

Description

technical field [0001] The invention relates to a multi-beam aperture splicing and combining system based on stable control of beam pointing, which can measure the optical axis position of each beam and control the closed-loop stability of beams to realize stable combination of high duty ratio and high precision beams. The multi-path stable combining system can be widely used in the fields of multi-path optical fiber and solid laser beam combining and launching, as well as the field of multi-path optical communication. Background technique [0002] With the continuous expansion of the application field of laser technology, multi-beam synthesis technology is required in the field of fiber laser and solid-state laser multi-beam synthesis emission, as well as in the field of multi-channel laser communication. Beam synthesis technology is to accumulate the energy of multiple laser beams. If the phase between the beams and the coherence between the beams are not considered, but s...
