Paper Abstract

In this paper, we are reporting for the first time on a spiker-sustainer XeCl laser operating at a PRF of up to 1 kHz. The laser is x-ray pre-ionized in the interest of pre-ionization homogeneity and in order to avoid contamination of the laser gas. A conventional flow loop was employed, having a maximum flow speed of 50 m/s at 3 bar, which translates into a clearing ratio of 2.5 at a PRF of 1 kHz. A pyroelectric energymeter (GenTec ED500) was used to measure single-shot energies. The pulse energy in repetitive mode and the pulse duration were observed with a calibrated vacuum photodiode. The spatial beam profile was recorded on photosensitive Dylux paper. Among the different spiker modes tested, a modification of the overshoot mode gave the best results in terms of efficiency, output energy, and overall laser stability.
