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 Dy3 or Nd3 were grown. LASER oscillation was observed from two crystals of CaWO4Nd. 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.
