Abstract

As is well known, in coherent anti-Stokes Raman spectroscopy (CARS), the frequency ω_R of molecular vibrations or rotations is determined by the difference in frequency of the applied laser beams with fixed (ω₁) and with tunable frequency (ω₂), i.e., ω_R = ω₁ − ω₂. For low resolution CARS experiments (∼0.1 to 1 cm⁻¹), it is usually sufficient to measure the frequencies of the two laser beams by means of a spectrometer which has been calibrated before using emission lines of discharge lamps. The accuracy in frequency determination applying this method is limited to be approximately ±0.1 to ±0.5 cm⁻¹.
