| Raman spectroscopy has long been recognized as a versatile tool in the studies of molecular structures because of its many advantages. For instance, Raman often requires minimal sample preparation and sampling is non-destructive. During the past decade, acousto-optic tunable filters (AOTF) have been applied as wavelength selective devices in Raman instrumentation. These studies utilized visible lasers. However, applications of UV-AOTF Raman have not been demonstrated. Possible reasons include lack of appropriate UV lasers and AOTFs in the past. Recent successes with a quartz AOTF having an output wavelength down to 200 nm, and the availability of compact deep UV lasers make this goal possible. The use of a compact pulsed deep UV laser with a quartz AOTF for Raman spectroscopy will be discussed. This spectrometer has several potential advantages. For example, the reduced power consumption and compact size of the AOTF and laser are suitable for NASA applications in space. |
