Abstract

We have measured the thresholds of stimulated Raman scattering in a number of gases using 20 ps pulses from a KrF laser system. Stimulated scattering has been observed with methane, hydrogen, ammonia and sulphur hexafluoride below 5 atm pressure using pulse energies up to 200 μJ. Under the same conditions, no stimulated scattering could be obtained in oxygen or nitrogen. Measurements agree well with transient stimulated Raman scattering theory.
