Rotationally resolved coherent anti-Stokes Raman spectroscopy by using a tunable optical parametric oscillator
Abstract:
A beta-barium borate optical parametric oscillator (BBO OPO) serves as the tunable source for coherent anti-Stokes Raman spectroscopy (CARS). Two variants of this approach are devised to make rotationally resolved CARS measurements of nitrogen in air. In the scanned CARS technique, the BBO OPO operates in its continuously tuned, narrow-band mode with injection-seeding control of OPO signal wavelength. In the other technique, a free-running BBO OPO is used for single-shot, multiplex CARS measurements.

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...
