Abstract
A laser for generating a coherent output beam with a frequency equal to the um or difference of the frequencies of two input pumping beams or the harmonics thereof. The laser includes a lasing medium of the type with an inverse Faraday effect resonance frequency f.sub.1, a laser cavity with the lasing medium positioned therein, two coherent light sources for generating pumping beams at frequency f.sub.1 and f.sub.2, where the f.sub.1 beam is circularly polarized, and an optical system for directing the pumping beams into the lasing medium.
