Abstract

The development of high-brightness laser array with the phase locking of many laser channels is one of the topical problems that opens up prospects for a significant increase of the output energy characteristics and the creation of composite laser aperture with high directivity and brightness. In this case, a decrease in the radiation exposure of the laser optical elements leads to an increase in their lifetime. The principles for the construction of multichannel laser systems based on the short or long-range coupling between the lasers and the injection of the reference signal for the phase locking of the controlled laser channels can be found in [1]. Althought the possibility for the phase locking of solid-state lasers is limited due to significant dynamic optical distortions of the active media at high-power pumping the phase-conjugated lasers are promising for phase locking due to real-time self-compensation of the distortions.
