RESEARCH ON PROPERTIES OF LASER DEVICES
Abstract
LASER amplification corresponding to a gain of 6% per meter was measured at 3 microns in cesium vapor optically pumped with light from a helium discharge lamp. Amplification and oscillation at 1 microns were measured in a helium-neon system based on collisions of the second kind. The amplification parameters, when optimized resulted in a gain of 9% per meter. Krypton-xenon and zinc vapor are other media utilizing collisions of the second kind which were investigated. Crystals of calcium tungstate containing either Dy(3+) or Nd(3+) were grown. LASER oscillation was observed from two crystals of CaWO4:Nd. Direct amplification of the output of a ruby oscillator in a second ruby rod was demonstrated. Three methods of achieving single pulse output from ruby oscillators are described. A pulse of 2,000,000 watts peak power was achieved by one method. A broadband emission was discovered in normally pink ruby (.04% Cr by weight). It accounts for 30% of the total emission, making the quantum efficiency unity. A theoretical analysis of the properties fo cube corner interferometers has been experimentally verified.
