DEGENERATE 4-WAVE MIXING IN EXCITED-STATES FORMED BY COLLISION ASSISTED TRANSITIONS
A degenerate four-wave mixing signal has been generated in atomic sodium vapour-argon mixtures by a laser tuned to the excited state transition 3 2P 1 2, 3 2-42D at λ568 nm. Population of the 3 2P levels is explained by excitation in the far wing of the collision broadened resonance line. The signal...
