Growth of beam perturbations by stimulated light by light scattering in the atmosphere

Low spatial frequency (small angle) components induced on an initially nearly plane wave optical field can be amplified by stimulated light by light scattering arising from molecular orientation. For sea level air and a laser intensity of 2 MW/cm(2) at 1microm, a maximum steady state gain of 7 x 10(...

Zusammenfassung:Low spatial frequency (small angle) components induced on an initially nearly plane wave optical field can be amplified by stimulated light by light scattering arising from molecular orientation. For sea level air and a laser intensity of 2 MW/cm(2) at 1microm, a maximum steady state gain of 7 x 10(-3) km(-1) is found for amplification at an angle of 10(-6) rad. The possible influence of this effect on the stimulated Raman scattering experiments of Henesian et al. is considered.
