Experiments are described in which a 1 mJ, 1 ps, 1200 nm seed laser beam is amplified by the interaction with an intersecting 350 J, 1 ns, 1054 nm pump beam in a low density 1 1019 /cm3 plasma. The transmission of the seed beam is observed to be enhanced by 25 when the plasma is near the resonant density for stimulated Raman scattering, compared to measured transmissions at wavelengths just below the resonant value. The amplification is observed to increase rapidly with increases in both pump… CONTINUE READING
