  • Two-stage power laser
    Patent number: 5570387
    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.

  • Method of etching a surface of an indium phosphide part
    Patent number: 4861423
    Abstract: A wafer of indium phosphide is disposed between two electrodes (102, 104) in a heated enclosure (100) into which ducts (110 and 112) admit nitrogen and ammonia. A high frequency electricity generator (108) forms a plasma between the electrodes which etches the exposed surface of the wafer. The invention is applicable, in particular, to forming semiconductor lasers emitting in the infrared for telecommunications purposes.
