【Abstract】 The parametric dependence of the output energies and the efficiency for theRaman conversion of XeCl excimer laser radiation in Pb vapor was studied.Pulses at Raman-Shifted wavelength,with 120 mJ energy and 2 MW peak power were obtained.The effects ofbuffer gas on the Stimulated Raman Scattering in Pb vapor are analyzed theoretically.Thetheoritical result shows that the effects consists of the collision effects between buffer gas atomsand Pb atoms and the absorbtion effects of buffer gas.The culculated result are in agreementwith that of the experiment更多还原
