Abstract

Recently, Lippi et al1 and Hemmer et al.2 observed amplification of a laser field propagating through a collection of high-temperature (~600 K), Doppler-broadened sodium atoms driven by an intense counterpropagating laser beam. They attribute the gain lo an atomic density grating (a periodic bunching of the atoms) formed by the aggregate effect of atomic recoil; a surprising result considering that the modulation depth of the density grating is expected to be quite small at this temperature.5 Nevertheless, their intriguing results agree qualitatively with recent analyses of this interaction.4
