ABSTRACT:
A laser cavity containing a mixture of nitrogen, N.sub.2, and mercury, Hg, gas is optically pumped by a lamp containing mercury to produce a laser output of 546.1 nm. The upper laser level is excited through optical pumping by a resonance lamp while the lower level which is a low lying metastable state is depopulated by collisional quenching.
