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.
