Title: Bernard Groussin: Innovator in Laser Technology
Introduction
Bernard Groussin is a notable inventor based in Les Ulis, France. He has made significant contributions to the field of laser technology, holding a total of 3 patents. His work focuses on high-power solid lasers and integrated circuits of semiconductor lasers, showcasing his expertise and innovative spirit.
Latest Patents
One of Groussin's latest patents is the "Two-stage power laser." This invention discloses 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 an integrated circuit that includes rods of semiconductor lasers alternating with grooves, with both elements being parallel. The invention involves incrusting the material of the solid laser bars into the grooves between the rods of semiconductor lasers. This material can be placed in hybrid form or deposited to create an integrated structure.
Another significant patent is the "Integrated circuit of semiconductor lasers." This disclosure relates to integrated circuits of lasers, wherein the linear arrays are supplied in series, with a return of current through the substrate. When the substrate is semi-insulating, only the first epitaxially grown layer is conductive. To reduce its electrical resistance, a surface film of the substrate is made conductive by the diffusion of a dopant. This innovation has applications in power semiconductor lasers.
