Title: The Innovative Contributions of Joel M Avidor

Introduction

Joel M Avidor is a notable inventor based in Rehovot, Israel. He has made significant contributions to the field of laser technology, holding 2 patents that showcase his innovative approach to solving complex problems in this area.

Latest Patents

One of Avidor's latest patents is the "Gas Laser Aerodynamic Window." This invention involves a contiguous pair of gas jet streams driven at subsonic velocity across the entire cross-sectional area of an annular laser beam. One of the jet streams has a shear interface with the interior gas of the laser, with its index of refraction matched to it. The other jet stream interfaces with the outside air, also having a matched refraction index. This matching minimizes optical distortion of the beam at the shear interfaces. Additionally, distortion produced at the boundary layer of the contiguous jet streams is minimized by equalizing their velocities. The design allows the jet streams to bend responsively to maintain a desired laser cavity pressure, effectively reducing window gas consumption.

Another significant patent is the "Method and Apparatus for Injecting Gas into a Laser Cavity." This invention addresses the need for fast and efficient mass transport of laser gas in a multiple-pulsed electric discharge laser (EDL). Avidor’s method involves injecting the laser gas through arrays of porous tubes with eccentric walls, tailored to introduce a non-uniform injection velocity. This design establishes a nearly irrotational flow that rapidly develops into a uniform flowfield downstream of the tube array. The enhanced heat transfer characteristics of the porous tubes also maintain a beneficially uniform gas temperature, ensuring good optical medium homogeneity.
