Title: Innovations of Pierre J Mathieu
Introduction
Pierre J Mathieu is a notable inventor based in Cap-Rouge, Canada. He has made significant contributions to the field of laser technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Mathieu's latest patents is the "Miniature Stimulated Raman Shifting Cell." This invention involves a Raman cell designed for shifting the wavelength of a laser pump beam. The cell contains a gaseous Raman medium at a pressure of 100-1000 PSIG. It features an input window for the pump beam at one end and an output window for the Raman shifted wavelength at the opposite end. The output window is a plane mirror coated with dielectric thin films, ensuring high reflectivity for the pump beam and partial reflectivity for the Raman shifted wavelength. The input window includes a lens that focuses the pump beam at the center of the cell.
Another significant patent is the "Stimulated Raman Laser of Amplifier Using Axicon Pumping." This invention comprises a Raman cell oscillator/amplifier arrangement that contains a high-pressure gas or liquid medium. It utilizes axicons at each end of the cell, with one axicon featuring an input window for the laser pump beam. The design allows the laser pump beam to be directed towards an extended line focus along the cell's axis, creating an efficient Raman gain region while avoiding issues like optical breakdown and Brillouin backscattering.
