Paper Abstract

Increasing interest has been shown in scaling excimer lasers to high average power either with a high energy per pulse or with a high repetition rate since their applications are very promising and attractive in several fields, such as materials processing, photochemistry, and so on. In order to cover a broad range of applications, the work at the ENEA Frascati laboratories has mainly been devoted to developing two different discharge-excited laser sources, one operating at - 10 J/pulse and a repetition rate of - 100 Hz, and the other at 1 J/pulse and a repetition rate of - 1 kHz. As an intermediate step, two x-ray preionized XeCl laser discharge devices were studied: one device has a discharge volume of 10 liters (10x10x100 cm3) (Laser:L) with a longi-tudinal gas flow mode in the discharge region, while the other operates in a transverse gas flow mode with a discharge volume of 0.45 liters (3x3x50 cm3) (Laser:S)*. Some of the experimental results obtained with the two devices are described in this report.
