ABSTRACT:
A multi-line NH.sub.3 laser is disclosed pumped by a multi-longitudinal mode and multi-transverse mode laser beam from a high-pressure CO.sub.2 laser operating on the R(30) 9.2 .mu.m transition. The resulting comb of pumping wavelengths simultaneously pumps several close-lying sR(5,K) transitions in ammonia from the symmetric ground state to the antisymmetric .nu..sub.2 =1 state, providing simultaneous lasing on a plurality of sP(7,K) transitions of different K-values. A plurality of sP(5,K) ammonia laser lines originating in the .nu..sub.2 =1 antisymmetric band and terminating in the depleted lower pump levels are also generated.
