High-power semiconductor chip laser array

Abstract

The invention discloses a high-power semiconductor chip laser array. The high-power semiconductor chip laser array comprises a pump light source system, a semiconductor gain chip and a microcavity lens array, wherein the semiconductor laser array forms a pump beam array after the semiconductor laser array is shaped by a shaping component; the pump beam array enters the semiconductor gain chip; and the microcavity lens array is used for forming a resonant cavity array and for being coupled with an output laser array. According to the invention, the gain medium is a semiconductor chip which can be self-designed according to the species of semiconductor materials, the ingredients of the materials, and the difference of the thicknesses of quantum wells, and the wavelengths of lasers are from visible lights to near-infrared lights, thus the defect that the wavelength of lasers emitted by the gain medium is relatively fixed in the prior art is overcome; the laser array has an unique advantage in application to aspects, such as optical integration, optical communications, optical interconnections and high-speed parallel computations; heat is dispersed to a plurality of units, thus the high-power semiconductor chip laser array is more beneficial to heat dispersion of a laser and can output higher total power; in addition, the high-power semiconductor chip laser array has the advantages of small volume as a whole, good stability, strong reliability and high efficiency.

Problems solved by technology

[0003] In the prior art, in order to increase the power of solid-state lasers, a solid-state thin-sheet laser using a diode laser array as a pumping source has appeared, and the output laser power after pumping is relatively high; although theoretically it is possible to increase the output power of the laser, the gain medium It is a common gain medium for general solid-state lasers, and the laser wavelength range is relatively single; the resonant cavity is composed of a reflector, a gain medium, and a transmission mirror, and the resonant cavity and beam shaping are independent, resulting in a laser with large volume, difficult heat dissipation, and large optical loss. Disadvantages, so the service life is lower and the efficiency is poorer
