  • STUDY OF THE GENERATION OF INTENSIVE LYMAN-ALPHA RADIATION BY SHIFTING THE FREQUENCY OF AN ARGON EXCIMER LASER BY STIMULATED RAMAN SCATTERING IN DEUTERIUM

Abstract

The electron beam pumped argon excimer laser is a powerful VUV light source at 126.1 nm. Failure of intracavity tuning to Lyman-alpha (121.6 nm) results from the low gain at 121.6 nm. However, there exists the possibility to shift the Ar*-2-laser line to Lyman-alpha by stimulated Raman scattering, if one uses the first order anti-Stokes line in Deuterium. This study investigates the requirements of the Ar*-2- laser with regard to power and luminosity necessary for an efficient Raman shifting to Lyman-alpha. A commercially available ArF laser (193 nm) was used to study the stimulated Raman effect in different gases (H-2, D-2, CH-4). The results indicate that the minimum luminosities required for shifting the Ar*-2-laser in Deuterium exceeds those presently achievable.
