Diode source of multibeam coherent laser emission

The proposed semiconductor sources of laser coherent emission are used in precision laser material processing (laser cutting, welding, drilling, surface melting, dimensional processing of various parts, laser marking and engraving), in laser devices for surgery and power therapy, in laser rangefinders, laser target designators, for realization of frequency-doubled lasers, and for pumping fiber and solid-state lasers and optical amplifiers. The main features of the proposed diode source of multibeam coherent laser emission (DSMCLE) with horizontal and vertical emission outputs (a particular case is the DSMCLE-VE) consist in an original and unobvious two-stage integrated combination of a single-mode (and single-frequency) master diode laser with diode optical amplifiers. At the first stage the integral connection of the master laser and the linear amplifier is realized, in this case the directions of the optical axes of propagation of emissions of said master laser and linear amplifier coincide. At the second s
