DYNAMIC OPTICAL PROPERTIES OF LASER MATERIALS.
Abstract
Dynamic optical distortions were studied in high quality ruby rods (0.05 percent Cr2O3). Radial temperature profiles, determined by non-resonant interferometric techniques, were level to about 5 percent. Radial gain profiles showed variations of 5 percent to 20 percent, depending on the pump energy. A plane polariscope was used to determine the effects of stress birefingence during the pump period. No significant depolarization was observed in ruby during the mian part of the pump period, but large birefringence effects were seen in Nd:glass. Thermal changes in length and refractive index were found to be the main source of dynamic optical distortions in ruby. The net effect of these distortions can be made small by use of properly designed cavities. (Author)
