A study of transient Raman amplification in H2 and D2
Abstract
Experimental and theoretical studies of transient Raman amplification (TRA) in H2 and D2 gas for both vibrational and rotational Stokes wavelengths are described. TRA was measured (using a 40-psec pump pulse at 532 nm and a 25-psec seed pulse at the appropriate Stokes wavelength) as a function of pump energy, gas pressure, and the relative timing of the pump and seed Stokes pulses. Stable gains of e exp 19 were measured in the small-signal regime, and first Stokes conversion efficiencies of 75 percent were observed. Relative pulse timing was found to be an important parameter for maximizing TAS.
