Ultraviolet prepulse for enhanced x-ray emission and brightness from droplet-target laser plasmas
(1996) In Applied Physics Letters 69(12). p.1683-1685- Abstract
- We show that an ultraviolet prepulse significantly enhances the water-window x-ray emission and brightness for a droplet-target laser plasma. By combining a 65 mJ, 120 ps, lambda = 532 nm main pulse with an up to 3 mJ prepulse, the emitted x-ray photon flux may be increased more than eight times. The resulting C VI lambda = 3.37 nm line emission is more than 3 x 10(12) photons/sr . pulse, corresponding to a conversion efficiency above 3%/line. The integrated spectral brightness is increased two times and is found to reach its maximum for different prepulse parameters than those resulting in maximum photon flux.
