U. Domiaty et al., NONLINEAR EMISSION IN SODIUM VAPOR UPON PULSED-LASER EXCITATION OF THE 4(2)P LEVELS, Applied physics. B, Lasers and optics, 59(5), 1994, pp. 525-531
Parametric four-wave mixing, stimulated electronic Raman scattering an
d amplified spontaneous emission cascades have been studied experiment
ally by single-photon resonant and near-resonant excitation of the 4 P
-2 levels of dense sodium vapour. The dependence of emission intensiti
es on laser detuning and exciting laser power is discussed.
