Integrated laser light source

Abstract

The invention relates to a laser light source, in particular to an integrated laser light source, and solves the technical problems that a current laser is difficult to implement a high-power output, the simple array arrangement can cause poor heat dissipation, output laser usually contains speckles and the optical power density is insufficiently high. The integrated laser light source comprises a reflection reactor optical coupling device and a laser transmitter system matched with the reflection reactor optical coupling device; the reflection reactor optical coupling device comprises a plurality of layers of reflective arrays which are axially arranged along a principal optic axis; and each reflective array comprises a plurality of reflecting surfaces arranged around the principal optic axis and a center reflecting surface positioned on the principal optic axis. The invention solves the problems of low optical power, low optical power density, poor heat dissipation, serious speckles and the like of a conventional high-power laser light source by the ingenious space arrangement of the reflecting surfaces and a laser transmitter; the outstanding technical effects are obtained; and the integrated laser light source is low in cost and easy to produce and operate.

Description

Technical field [0001] The invention relates to a laser light source, in particular to an integrated laser light source. Background technique [0002] In the fields of high-brightness laser display and high-power laser processing, the requirements for laser light power are increasing, and it is difficult to achieve high-power output of a single laser light source in the prior art. Especially the semiconductor laser, although it has the advantages of small size, high photoelectric conversion efficiency, simple structure, stable operation, etc., due to the low output power, multiple lasers must be coupled and integrated to achieve high power output. Simple array integration will cause defects such as large volume, low optical power density, large scattering angle, and poor heat dissipation characteristics. How to achieve high power, high power density, and small scattering angle laser light source has become one of the difficult problems in the fields of laser display and laser pr...
