Abstract

A methane Raman shifter is used for frequency conversion of the second harmonic of a pulsed 532 nm Nd:YAG laser generating Raman-shifted Stokes and anti-Stokes lines ranging from 237.3 nm to 995.4 nm. Methane pressure dependence of the output power and conversion efficiencies of the generated Stokes and anti-Stokes lines were investigated. Input power dependence of the conversion efficiencies of the Raman lines at methane pressure of 120 psi is also presented. The output power of the generated UV and NIR lines ranged from tens of μW to several hundreds of mW at maximum laser input power.
