Uncooled GaAlAs Laser Illuminator for Night Vision Applications

Abstract

A lightweight, man-portable semiconductor laser illuminator was described that represents the first application for arrayed GaAlAs laser diodes operating at 300 K. This prototype model clearly demonstrates the feasibility of radiation convection cooled illuminators producing radiant power outputs in the wavelength region of 850 nanometers to match the spectral sensitivity of S- 25 image intensifier tubes. This illuminator emitting 80 milliwatts with an overall power efficiency of 0.53% weighs only 1.91 pounds. (Author)
