Abstract
A high average power, picosecond pulse XeCl excimer laser system has been demonstrated. By using spatial filtering of the XeCl preamplifier, and by forming pulse bursts of 16 pulses with 2-ns pulse spacing, amplified spontaneous emission has been successfully suppressed in the output of the final amplifier stage. On average, each pulse in the burst is amplified to a level of 15 mJ, corresponding to approximately twice the saturation fluence for XeCl. Peak power in the picosecond pulses is 1.5 GW at 10 ps pulse duration, and the average power of the system is 68 W at 300 Hz burst repetition rate. These pulse bursts have been focused on a copper tape target to generate a laser-produced plasma which emits an x-ray power of 2 W into 2(pi) steradian solid angle, in a spectral band from 9-13 angstrom.
