Titel
Optical parametric oscillator -OPO-. A compact and fast tunable Stokes source in CARS spectroscopy
Abstract
An optical parametric oscillator (OPO) is employed as a broadband Stokes source for coherent anti-Stokes Raman spectroscopy (CARS). First studies show that this OPO-CARS configuration is useful because of several practical reasons (published in ref. 1). The OPO allows a fast and comfortable spectral selection or enhancement of excited spectral bands. Spectral fluctuations and their influence on the accuracy of single pulse thermometry for OPO-CARS and the conventional broadband dye laser approach are compared. First studies show that OPO-CARS offers a similar accuracy in temperature determination and a great advantage of handling.
