New measurements of the nonlinear, nonequilibrium optical (1.06m) properties of the germanium solid-state plasma are presented. Single pulse transmission has been measured as a function of incident pulse energy at sample temperatures of 105 K and 297 K. In addition the relative transmission of a probe pulse as a function of time delay after an excitation pulse has been measured for three different excitation pulse energies and two temperatures. A model which explains the observed behavior of germanium under intense radiation is briefly, qualitatively described, and theorectical curves are plotted with the experimental data. 1976.
