Abstract :
Laser sources in the ultraviolet (UV) spectrum, specifically in the range from 250 nm to 350 nm, are of great interest for long range remote fluorescence spectroscopy. We report here our experimental results of efficient (87%) rotational stimulated Raman scattering (RSRS) and vibrational stimulated Raman scattering (VSRS) using the second and fourth harmonic from a phase conjugated master oscillator power amplifier Nd:YAG laser with high beam quality. We present experimental data obtained for hydrogen and deuterium gases used as Raman media
