Abstract

The results of experimental investigations of an FIR laser on hot holes in germanium in constant crossed electrical and magnetic fields in the Voight configuration are presented. Similar studies have been carried out before, mainly for the Faraday configuration. The Voight configuration provides a greater intensity, a greater (E,H) region and a wider spectral range of generation than the Faraday configuration. A new type of injectionless FIR laser is proposed-a heavy hot-hole cyclotron resonance laser. Calculation of optical gain, alpha _gain, spectral dependence is carried out by balance equations of power and number of particles. The Monte Carlo method is used to calculate light and heavy hot-hole distribution functions and the value of alpha _gain. Some advantages of such lasers are presented in comparison with an FIR laser in constant crossed electrical and magnetic fields.
