β¦ Synopsis
The use of CARS as a probe of gas phase molecular concentrations has been extended into the picosecond regime. A double-beam configuration employing singe pulses from a mode-locked Nd:glass laser has allowed measurement of Nz ('Q, u = 0) pressures to an accuracy of better than 10% with 8 ps time resolution. This technique shows promise for the study of dy%unics of gas phase photodissociation processes

The dependence of CARS susceptibilities on molecular orientation is considered for a diatomic or symmetric-top molecule. The angular distribution of the internuclear axis during an excitation time interval that is short compared with a simple molecular rotation was investigated. The part of the mole
## Abstract In this paper recent research progress on the use of Coherent AntiβStokes Raman Scattering (CARS) in Raman lasers and Raman wavelength converters is reviewed. The latest insights in the physical nature and behavior of CARS are addressed, and the recent performance breakthroughs in CARSβ
## Abstract Coherent antiβStokes Raman scattering (CARS) microscopy, or microβCARS, is becoming more and more popular to identify chemical species with notable threeβdimensional resolution. In view of this important application, the present work tries to extend the analysis of cavity effects that a
