ABSTRACT:
The disclosure is a high-power solid laser in which an emissive array of semiconductor lasers in a first stage pumps a solid YAG-type laser in a second stage. The structure of the emissive array, which is an integrated circuit, includes rods of semiconductor lasers alternating with grooves, the rods and grooves being parallel. The invention involves incrusting the material of the solid laser bars into the grooves between the rods of semiconductor lasers. This material is either placed in hybrid form or deposited to make an integrated structure.
