Abstract
A single-color pump-probe system has been commissioned at the Novosibirsk free electron laser. The laser emits a tunable monochromatic terahertz radiation. To prove the proper system operation, we investigated the time-resolved absorption of a sample of n-type germanium doped with antimony, which was previously investigated at the FELBE facility, in the temperature range from 5 to 50 K. The measured relaxation time amounted to about 1.7 ns, which agreed with the results obtained at FELBE. The results of pump-probe measurements of non-equilibrium dynamics of hot electrons in a germanium crystal at cryogenic temperatures are presented for wavelengths of 105, 146 and 150 μm.
