Paper Abstract

Very little research on optically pumped FIR-ringlasers has been reported in the past, despite the fact that such lasers have proven to be more stable FIR-monochromatic sources than the usual standing wave resonator types (Heppner, Weiss 1978).

The ringlaser offers much better isolation between the pump and the FIR-laser due to the elimination of interaction between the two. This is similar to pumped dye ringlasers in the visible part of the EM-spectrum.

Unlike most ringlasers in the visible range unidirectional emission is a general feature of FIR-ringlasers. Hence an optical diode is not required to suppress simultaneous bidirectional operation.
