Nd:YAG二倍频激光(532 nm)泵浦H₂中的受激喇曼散射产生多级斯托克斯.其中一级、二级和三级斯托克斯的最高量子转换效率分别可达66%,60%和19%.在0.44 MPa下,可同时获得1 579 nm(19%),954 nm(30%),683 nm(33%),532 nm(14%),436 nm(3.7%)和368 nm(1.4%)的多波长输出.H₂压力对多级斯托克斯转换有显著影响:高气压有利于产生高效的一级斯托克斯,而低气压则适合于高级斯托克斯和反斯托克斯的产生.

Multi-order Stokes is generated in H₂ pumped by a pulsed Nd:YAG laser at 532 nm.Maximum energy conversion efficiencies as high as 66%,60% and 19% are attained for the first,second and third Stokes respectively.Under 0.44 MPa H₂,significant multi-wavelength outputs can be obtained simultaneously with quantum distribution of 19% at 1 579 nm,30% at 954 nm,33% at 683 nm,14% at 532 nm,3.7% at 436 nm,and 1.4% at 368 nm.High-pressure H2 is found to be the best for highly efficient first Stokes conversion,while low-pressure H₂ is proved suitable for higher order Stokes and anti-Stokes generation.
