Abstract :
Time evolution of the nonequilibrium hole distribution function is followed by numerical integration of Boltzmann´s equations in p-Ge taking into account anisotropic band structure. Both the hole-burning and light-light modulation experiments of Keilmann can be reasonably explained by a simple model. Subpicosecond relaxation time for these processes is obtained in good agreement with Keilmann´s estimate.
