High Resolution Coherent Anti-Stokes Raman Spectroscopy of Deuterium Gas.
Abstract
Coherent anti-Stokes Raman spectroscopy (CARS) is a third order nonlinear optical mixing process primarily used to probe gases. Two laser beams interact with the medium being studied producing a weak, third beam with a higher frequency than either of the lasers. High resolution cw coherent anti-Stokes Raman spectroscopy (CARS) was performed in molecular deuterium gas. Single mode argon ion and ring dye lasers were used to make accurate measurements of the Raman linewidths of the Q(0) through Q(4) transitions. These lines were examined at room temperature at pressures ranging from 0.35 to 20 atmospheres. The pressure broadening coefficient and the self diffusion coefficient of each line were obtained in this study and compared with other work. Additionally, the transition frequency of each line was measured and the frequency shift coefficients were obtained.
