Two-stage high-power laser.

摘要

The invention relates to a solid state laser of high power, associating an emissive plate (12) of semiconductor lasers (4) (first stage) which pump a solid laser (13) of type YAG (second stage). BR/ The structure of the emitting plate (12) which is an integrated circuit, comprises an alternation of strips (2, 3) of semiconductor lasers (4) and trenches (9) between these strips (2, 3) which are parallel to each other. The invention consists in embedding the material of the solid laser bars (13) in the trenches (9) which separate the semiconductor lasers (4). This material is either reported in hybrid form or deposited in integrated form. BR/ Application to lasers of very high luminous energy.
