· Phys. Rev. A; (United States)
Experimental verification of reduced stimulated Brillouin scattering (SBS) is reported for multiline CO/sub 2/ laser radiation interacting with high-intensity plasma. For long-pulse (40-nsec) irradiation SBS was observed to decrease from 15% to a negligible level when the spectrum of the incident laser pulse was changed from 1 to 2 more well-separated frequencies. Results for both long- and short-pulse multiline laser conditions are in general accord with the expected behavior for varying ..delta omega../..gamma../sub 0/, where ..delta omega.. is the frequency separation and ..gamma../sub 0/ is the homogeneous growth rate.
