Abstract

Metastable inversions in the ¹S₀ state of the group VI elements (oxygen, sulfur, and selenium) are proposed as host media for a new class of anti-Stokes Raman laser. Selective photodissociation of N₂O, OCS, or OCSe with appropriate VUV wavelengths can create ¹S₀ inversion densities in excess of 10¹⁶ atoms/cm³. Using this population inversion to upconvert tunable input lasers should result in the creation of efficient, high-power lasers over the 100–206-nm spectral region.
