Generation of nanosecond THz pulses using a high gain ring resonator with a semiconductor switch

A [Formula: see text] quasi-optical ring resonator consisting of an input coupler and three mirrors has been designed tested. low-loss silicon wafer in the provides output coupling stored power when irradiated by a pulse from laser. The created pulses excited continuously operating source, achieving gain 16. In fully tuned ring, higher is achievable. If was used with pulsed source having length several times fill time, could be as efficient compressor similar high gain. wide range applications, including, at low power, spectroscopy and, testing accelerator structures materials.
