Raman shifting of picosecond light pulses in hydrogen gas
Abstract:
Picosecond light pulses are used to generate multiple wavelengths by means of stimulated Raman scattering. A review of the processes involved is presented, followed by a discussion of the experimental apparatus. Stokes and anti-Stokes Raman-shifted lines arising from vibrational and rotational transitions are observed. The polarization of the incident pump laser considerably affects which wavelengths are observed. Some vibrational Raman lines exhibit a splitting that is due to scattering from different initial H(2) rotational states.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
