高阶喇曼辐射的弛豫振荡和光束特性

Raman shifted convesion from AS3(226 nm) to S5 (849 nm) have been observed in high pressure H2 pumped by high power XeCl eximer laser radiation (308 nm). Its photonconversion efficiency into blue-green region (S3, 499nm) was obtained up to 39%. Relaxation oscillations of higher order Raman shifted e
