Laser Design and Applications

A neodymium-glass laser device is described which employs amplified spontaneous emission in a nonresonant system to obtain a high brightness output pulse. The spontaneous avalanche obtained was in a 70-nsec pulse of approximately 1-GW power confined to a 1-mrad-full-angle beam. The output brightness was sufficient to produce unfocused air breakdown. Included are design criteria and an analysis of the characteristics of the avalanche pulse.
