Multifrequency laser emission generated by two-color stimulated Raman effect using a single-frequency laser beam and
Abstract:
A single-color circularly polarized laser beam is focused into pressurized hydrogen to generate rotational stimulated Raman emission. After being corrected to a linearly polarized beam, this two-color laser beam is passed through a dye amplifier and is focused into pressurized hydrogen, again to generate multifrequency laser emission by the two-color stimulated Raman effect. The laser beam is further confined in a resonator, which enhances intracavity intensity leading to increased efficiency. In these experiments, more than 11 rotational lines are generated simultaneously at 5 atm, and many additional vibrationally shifted rotational lines are generated at 9 atm.

01:26Raman 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...
