C.A.R.S. monitor of laser induced dissociation of molecules and clusters in supersonic jet

Abstract

A pulsed molecular beam was built to study laser induced dissociation of cold molecules and clusters in different wavelength regions from IR to UV. The CARS (Coherent Anti-Stokes Raman Spectroscopy) diagnostic technique was chosen to characterize the molecular beam and measure parent decomposition, as well as, cluster dissociation from the attenuation of spectrally resolved Raman active vibrations. Some fragments were to be detected in the investigated wavelength range. A suitable low resolution CARS spectrometer was therefore built to detect single shot CARS signals in a wavelength range of about 40 nm in the blue spectral region, and this device was combined with the molecular machine. This paper describes the key deign and operating features of this equipment and presents and discusses the beam characterization results using molecular jets of pure CH/sub 4/.
