Research Studies on Short Wavelength by Selective Auger Processes
Abstract
Efforts are divided into two areas: (1) development of short wavelength coherent sources and (2) studies of lasers without inversion. In the first area, gain in the vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) was observed in the in Xe, Zn, Kr, Cs, and H2 gases. Methods for saturating the laser transitions in Xe and Cs were developed and produced microjoule level fully saturated outputs at 109 nm and 96.9 nm, respectively. Efforts to construct the next generation laser driver for such studies were also completed during this time period. In the second area, theoretical studies of different methods for creating transparency in atomic vapors were explored. Various applications of these transparencies were investigated, including the possibility of systems which would exhibit laser gain without the necessity for population inversion and the enhancement of nonlinear optical processes in the presence of such a transparency. Experiments demonstrated enhanced sum-frequency generation of 104.8-nm radiation with a naturally occurring transparency in Zn vapor.
