Optically-pumped group IIB atomic vapor lasers emitting at discrete wavelengths shorter than 230 nm are disclosed. This laser device utilizes an active medium comprising a mixture of a group IIB atomic vapor and one or more buffer gases placed within a doubly-resonant optical cavity that enables the realization of a population inversion between the first <1>P1 level and the <1>S0 ground level of the group IIB atoms. The laser may operate in a pure continuous-wave mode, or in a high-repetition pulsed mode, at DUV wavelengths of ~185 nm (mercury), ~229 nm (cadmium) and ~214 nm (zinc).
