Title: Claude Carriere: Innovator in Laser Technology
Introduction
Claude Carriere is a notable inventor based in Marcoussis, France. He has made significant contributions to the field of laser technology, holding a total of 2 patents. His work focuses on high-power solid lasers and innovative etching methods for semiconductor materials.
Latest Patents
One of Carriere's latest patents is for a two-stage power laser. This invention features a high-power solid laser where an emissive array of semiconductor lasers in the first stage pumps a solid YAG-type laser in the second stage. The structure of the emissive array is designed as an integrated circuit, consisting of rods of semiconductor lasers alternating with grooves, all arranged in parallel. The invention involves incrusting the material of the solid laser bars into the grooves between the rods of semiconductor lasers, which can be placed in hybrid form or deposited to create an integrated structure.
Another significant patent is related to a method of etching the surface of an indium phosphide part. In this process, a wafer of indium phosphide is positioned between two electrodes within a heated enclosure. Nitrogen and ammonia are introduced through ducts into the enclosure. A high-frequency electricity generator creates a plasma between the electrodes, which etches the exposed surface of the wafer. This invention is particularly applicable for forming semiconductor lasers that emit in the infrared spectrum for telecommunications purposes.
