Paper Abstract

1. Cyclotron resonance lasers. The tunable cyclotron resonance (CR) lasers that have been made recently are perspective devices for submillimeter spectroscoiDY C1-3D. The lasers are single germanium crystals in the form of maraileleDilDeds with a typical size of 4mmx5mmx2Omm supplied with ommic contacts and provided by an outer Fabri-Ferot cavity. All the system is maintained in a superconducting solenoid at liquid helium temperature. The laser operation is based on the property of a hot hole system in germanium to produce the population inversion of light hole Landau levels in strong crossed electric and magnetic fields. The emission spectrum has a single line of 0.2 1/cm wide, which can be continuously tuned in the range from 110 to 360 mkm (frequency from 28 to 91 1/cm). The radiation power of the pulse is 0.5 W and the pulse duration is 0.1 - 0.5 mks. The laser is small enough to be placed in a standard helium transport cryostat which permits CR laser application outside tne laboratory, for example, in a vehicle. Continuously tuning in a wide frequency range provides a unique possibility for laser application in atmospheric monitoring, quality tests of semiconductor materials in research, etc.
