The application of low-power cw laser sources in obtaining high-resolution stimulated Raman spectra (SRS) of the Q01 transition in molecular hydrogen shows a motionally narrowed minimum linewidth of 250 ± 5 MHz.Abstract:
We report the application of low-power cw laser sources in obtaining high-resolution stimulated Raman spectra (SRS) of the Q01 (1) transition in molecular hydrogen. Fully resolved spectra of both the real and the imaginary parts of the Raman susceptibility, obtained with a resolution of <25 MHz, show a motionally narrowed minimum linewidth of 250 ± 5 MHz. The cw SRS techniques reported herein should find a variety of applications in high-resolution Raman studies.read more

William K. Bischel,Mark J. Dyer +1 more
TL;DR: In this paper, the absolute Raman gain for the Q(1) vibrational Raman transition in H2 at 4155 cm−1 has been measured at pump (Stokes) wavelengths of 532 (683), 477 (594), and 307 (351) nm using a pulsed pump and a cw probe laser, both of which were single frequency.

Phase retrieval approach for coherent anti-Stokes Raman scattering spectrum analysis
TL;DR: In this article, a noniterative phase retrieval method for coherent anti-Stokes Raman scattering spectrum analysis is presented, which facilitates the computation of the real and imaginary parts of the effective third-order susceptibility χ when only its modulus is known.

Simultaneous Effect of Doppler and Foreign Gas Broadening on Spectral Lines
TL;DR: By using the classical Fourier integral theory, an expression is given for the shape of a spectral line, broadened by phase changes due to collisions and by actual changes in velocity of the emitting particles resulting from collisions as mentioned in this paper.
