The Nonlinear Optical Processes of OPSE,SHRS,FWPM and Their Competitions
The complex nonlinear optical process induced by two-photon-resonant excitation of Na 3S-4D has been thoroughly studied and the generated coherent radiation in the vicinity of 2.34μm measured and analysed.Based on the observation of forward and backward output it is believed that the complex process is composed of the optical-pumped stimulated emission (OPSE),stimulated hyper-Raman scattering (SHRS) and four-wave parametric mixing (FWPM).They often coexist simultaneously,each dominating over the others under different conditions,and there are obvious competitions among them.By adjusting experimental conditions,such as the temperature of medium,frequency of input light and interaction length,high conversion efficiency has been achieved.In this work the generated coherent 1R radiation centered at 2.34μm was tunable in 300cm-1,with a peak Dower of 100 kW,and an efficiency of 2%.18 new coherent UV lines were observed for the first time
