Quantitative Investigations of the Stimulated Raman Effect Using Subnanosecond Light Pulses

Abstract

Stimulated Raman emission of high conversion efficiency was observed in a traveling-wave system. Using laser pulses of shorter duration than the lifetime of the acoustic phonons, stimulated Brillouin scattering could be eliminated as a competing nonlinear process. Good quantitative agreement was found between existing theory (which was extended to real light beams) and experimental observations.
