Laser emission, consisting of three primary colors, is generated by frequency conversions of the second-harmonic emission of a picosecond (120 ps) Nd:YAG laser by means of stimulated Raman scattering and subsequent four-wave Raman mixing in molecular deuterium. In the double-pass configuration, the fundamental beam (532 nm, 14.16 mJ, 100%) is converted to blue (459 nm, 1.71 mJ, 12.1%), green (532 nm, 7.04 mJ, 49.7%), and red (632 nm, 4.90 mJ, 34.6%), resulting in a total conversion efficiency of 96.4%.
由三种原色组成的激光发射是通过皮秒（120皮秒）钕钇铝石榴石激光的二次谐波发射，借助受激拉曼散射以及随后在分子氘中的四波拉曼混频进行频率转换而产生的。在双程配置中，基频光束（532纳米，14.16毫焦，100%）被转换为蓝光（459纳米，1.71毫焦，12.1%）、绿光（532纳米，7.04毫焦，49.7%）和红光（632纳米，4.90毫焦，34.6%），总转换效率为96.4%。
