Two-Photon Resonant Optical Processes in Atomic Potassium

Not Accessible

Your library or personal account may give you access

Abstract

Four-wave and six-wave optical processes using the potassium ns2S1/2 states (7 ≤ n ≤ 20) are investigated with input beam provided by a pulsed dye laser pumped by a frequency-doubled Nd:YAG laser. The beam is focused into a heat-pipe oven containing potassium vapor (nk ≈ 1016 cm−3). More than 120 coherent UV or near-UV lines between 288 and 422 nm are generated through the processes ωUV ± ωIR = 2ωl and ωUV + ωIR′ + ωIR" ± ωIR'" = 2ωL.
