Abstract:

A high resolution infrared cavity ringdown laser absorption spectrometer has been developed to study proposed HEDM molecules and metal containing clusters. Using a novel tunable pulsed Alexandrite ring laser, we are able to generate tunable visible radiation with ca, 40 MHz bandwidth. This tunable visible light is downconverted to the infrared using stimulated Raman scattering in H2 and D2. With this system, tunable radiation from the UV to the far infrared can be generated with ca, 100 MHz bandwidth. We will test this system using our pulsed supersonic laser vaporization source to study both metal and carbon containing species. Infrared Cavity Ringdown Spectroscopy has also been used to study water clusters in both pulsed supersonic beams and pulsed discharged nozzles.
