Optical quenching of metastable molecular species and the generation of tunable broad-band stimulated emission in the UV is considered for molecular hydrogen. A detailed theoretical analysis is summarized and a Study of the optical energy extraction process, using off-resonant optical pumping from the metastable state c^{3}\Pi _{u} to the dissociative continuum state b^{3}\Sigma +_{u} , is presented. Earlier experimental work is discussed, and numerical results for the case of off-resonant pumping are presented.
