Abstract:

Recent progress in developing KrF laser pumped Raman lasers has shown their potential as X-ray laser drivers. The combination of short wavelength (268 nm) with low beam divergence and high beam intensity gives the possibility of very high focused intensity in very narrow line foci. An 8 cm × 8 cm beam combining Raman amplifier in the Sprite system has generated 0.4 TW, 12 ps pulses with 20 μrad beam divergence. A 10 μm wide line focus has been produced and plasmas from a NaF target have been studied at irradiances up to 3 × 1014 W cm-2. Numerical simulations suggest that the Sprite system should be able to produce high recombination gain in F IX at 8.1 nm and that larger scale KrF pumped Raman lasers which are being considered for future UK and European facilities would be ideal drivers for Mg XII at 4.5 nm.
