Hybrid lasers produced in potassium vapor by off-resonance pumping
Pulsed amplified emissions are observed at or near atomic transitions cascading down from the K(6S) and K(4D{sub 5/2}) states, when a pulsed dye laser is tuned near the K(6S{l_arrow}4{sub 3/2,1/2}) and the K(4D{sub 5/2}{l_arrow}4P{sub 3/2}) transitions. Emissions are suppressed when the pulsed dye laser is tuned to the K(4D{sub 3/2}{l_arrow}4P{sub 5/3,3/2}) transitions. The pulsed dye laser is used to excite molecules in a heat-pipe oven from high-bring ro-vibrational levels in the K{sub 2}(X{sup 1}{Sigma}{sub g}{sup +}) ground state to ro-vibrational levels in the K{sub 2}(B{sup 1}{product}{sub u}) state that predissociate to K(4S) and K(4P) atoms. The transitions can be pumped when the laser is tuned sufficiently close to the atomic resonances. We discuss the non-linear mechanisms responsible for the observed emissions. Emissions cascading down from the K(4S) state were first reported by Wang et al.
