Abstract
A unique high-power laser system is described that is based on stimula ted Raman scattering in methane. KrF-laser pump beams of 10-ps duratio n are confined in a square-section light guide and amplify a 268-nm St okes-shifted beam to 0.5 TW with extremely low prepulse. The near-diff raction-limited beam quality gives a peak brightness of >10(20) W cm-2 sr-1.
