INTERFEROMETRIC PHOTOGRAPHIC TECHNIQUES FOR RECORDING OPTICAL PATH LENGTH VARIATIONS IN PUMPED LASER RODS.

Abstract

The report describes some unique photographic techniques developed during an investigation of thermal effects occurring in solid-state laser materials (Nd(+++) glass and ruby) during the pumping period. An experimental approach is described for the investigation of the interaction of a high-energy laser beam with the atmosphere. Two novel high-speed cameras designed specifically for these investigations are discussed in detail. Experimental results are shown from which conclusions concerning optimum pumping arrangements, rod characteristics, and doping concentrations can be drawn. (Author)
