Abstract

The progress established over the last decade in creation of UV radiation sources and highly sensitive multichannel detectors made it possible to successfully conduct the experiments in UV Raman spectroscopy with application to fundamental and applied studies in biology and material science. Among these are studies of the protein structure and dynamics along with diamond film growth. In these experiments, CW or pulsed UV radiation sources are normally used. Argon-and Crypton-ion CW frequency-doubled lasers. Nd:YAG pulsed lasers with harmonic generators and non-linear optical converters, based on stimulated Raman scattering (SRS) in gases, allow generation of radiation at a limited number of wavelengths, most of which lie in the λ ≥ 230 nm region. Dye-lasers excited with the second harmonic radiation of Nd:YAG- and XeCl-lasers allow continuously-tunable radiation to be generated in the λ ≥ 200 nm region. These laser systems, however, are very complicated.
