Abstract

Potassium 4S_1/2 - 6S_1/2 two-photon excitation initiates the emission of several internally generated photons. For the first time two emission lines one close and one below the potassium 4P_3/2 level are reported. Radiation emitted below the 4P_3/2 - 4S_1/2 level is due to a Parametric Four Wave Mixing (PFWM) process initiated by the internally generated radiation from 5P_3/2 - 4S_1/2 level. The line emitted close to the 4P_3/2 level is produced by a two-step Four Wave Mixing (FWM) process. Direct one photon driving of 4S_3/2 - 4P_3/2 transition produces similar to HEP radiation.
