A combined pure rotational coherent anti-Stokes Raman scattering (PRCARS) and vibrational CARS (VCARS) system has been developed. In this system two beams, a broadband beam centered at 607 nm and the frequency-doubled Nd:YAG output at 532 nm is used to generate the PRCARS signal. A second 532 nm beam is used along with the other two beams to simultaneously generate the N(2) VCARS signal using a standard phase-matching scheme.
已经开发出一种组合的纯旋转相干反斯托克斯拉曼散射（PRCARS）和振动 CARS（VCARS）系统。在该系统中，使用两束光，一束宽带光，中心波长为 607nm，另一束是频率加倍的 Nd:YAG 输出的 532nm 光，用于产生 PRCARS 信号。第二束 532nm 光与另外两束光一起，使用标准的相位匹配方案，同时产生 N(2)VCARS 信号。
