Stimulated Raman gain scattering in planar dielectric waveguides.
We have measured the vibrational Raman spectrum of a 1.2-microm-thick polystyrene film by using this film as an optical waveguide in a waveguide-stimulated Raman gain experiment. A gain factor of 1.3% was measured for the strong benzene mode at 1002 cm(-1). This value is in reasonable agreement with theoretical predictions.

The stimulated Raman gain effect in planar dielectric waveguides is analyzed for the study of thin layers. Calculations show high gain factors and predict the possibility of detecting monolayers. Compared with those for methods based on ref lection, the gain can be 4 orders of magnitude higher for a monolayer of benzene. It is concluded that waveguide stimulated Raman gain spectroscopy is a pro...
متن کاملHigh-Resolution Stimulated Raman Gain Spectroscopy of Parahydrogen Crystals
High-resolution stimulated Raman gain spectroscopy of the Q1(0) transition of para-H2 crystals with varying ortho-H2 concentrations is reported. A crystal containing 0.06% of ortho-H2 showed a single sharp Raman transition with the width of less than 7MHz. The Raman signal became broader with increasing concentration of ortho-H2 . At the concentration of 2%, the spectrum splits into a doublet. ...
متن کاملStimulated Raman gain scattering in thin planar dielectric waveguides: erratum.
In our recent Letter 1 a numerical error was introduced in the calculation of the gain G 0. The values of the gain G 0 given in Figs. 2 and 3 should be multiplied by a factor of 5 to yield the correct values. Since this results in a gain that is even larger than that given in the Letter, it by no means alters the discussed ideas and conclusions.
متن کاملStudy of Loss Mechanisms and Stimulated Raman Emission
This report summarizes work, done at Philco Applied Research Laboratory under Contract Nonr-4850(00). Extensive measurements were taken on the conversion efficiency and threshold of stimulated Raman emission in benzene, nitrobenzene, toluene, and carbon disulfide. It has been shown that the self-focusing action of a laser beam is responsible for the onset of stimulated Raman emission.
