Development of a simplified dual-pump dual-broadband coherent anti-Stokes Raman scattering system.

A dual-pump dual-broadband coherent anti-Stokes Raman scattering (CARS) setup for simultaneous pure rotational and vibrational CARS is further developed by reducing the experimental efforts due to the use of only one detection system. With this system dual-pump CARS for probing ro-vibrational transitions of N(2)/CO/H(2) and dual-broadband CARS for pure rotational transitions of N(2)/O(2)/CO/CO(2) are applicable simultaneously. In this work the improvements to the setup and the data evaluation are described.
