Abstract

A β-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.
