LASER RADAR DEVELOPMENT.
Abstract
Several Q-switching experiments were conducted with the cored Nd:YAG. The 0.5- by 4-inch cored YAG rod was operated Q-switched at repetition rates up to 25 pps, with energy outputs of 200 to 300 millijoules per pulse. The head is capable of higher repetition rates, but the present energy storage system is not. The Q-switched operation is still limited by the short operating life of the Kodak saturable-filter dyes, even though we were able to extend the lifetime by a factor of 10 with better UV shielding. A brief examination of the major factors that determine the degradation by atmospheric turbulence of the performance of a laser radar is presented. Also the design and construction of a second-generation RGI system capable of illuminating and imaging a diffusely reflecting object in a water background at one mile with atmosphere-limited resolution is considered.
