Abstract
The nonlinear optical properties of a high-purity germanium wafer have been measured at 1.06 μm using picosecond pulses from a mode-locked neodymium:glass laster. By using such pulses we are also able to probe the hot electron distribution in order to obtain information on the ultrafast carrier relaxation times.Keywords
