DISPERSION EFFECTS IN LASER AMPLIFIERS.
Abstract
It has been shown that the Rytov approximation is severely limited in its applicability to long distance optical propagation in the atmosphere. A new and powerful boundary layer calculational technique has been developed and applied to the problem of scattering of electromagnetic waves from convex cylinders near grazing incidence. Multigigacyle acoustic waves were generated in crystalline solids by giant pulse ruby laser radiation; several unsuccessful attempts were made to probe these waves with Bragg-scattered gas laser radiation. However, multiple wavelength shifts in stimulated Brillouin scattering from quartz were observed; it was established, by time resolved interferometry, that these shifts result from an iterative process.
