Abstract
A collision-assisted two-step two-photon pump mechanism for generating a population inversion among the 5 2S and 4 2P levels in atomic sodium is reported. By tuning a pulsed dye laser to the 3 2P to 5 2S resonances IR laser emission on the 3.415 μm (5 2S 1/2-4 2P 3/2) and on the 3.408 μm (5 2S 1/2-4 2P 1/2) lines is observed. The conversion efficiency is e stimated to be 5% and up to 5W IR peak power is observed in the present experimental setup.
