Laser-induced breakdown in H{sub 2} gas at 248 nm
- Laser Laboratory, Institute of Research and Innovation, 1201 Takada, Kashiwa, Chiba 277 (Japan)
Measurement of optical breakdown threshold in hydrogen gas with a KrF excimer laser at 248 nm is presented. The result shows a sharp increase of the threshold intensity at a few atmospheres of gas pressure when a focusing lens with a longer focal length is used. This enhancement is partially explained in terms of the influence of pump beam depletion in stimulated Raman scattering. {copyright} {ital 1996 Optical Society of America.}
