Abstract
This paper describes the laser performance of an X-ray preionized ten-liter volume, electron-avalanche discharge XeCl system, operated at dc charging voltages of up to 70 kV both with and without X-ray preionization. An output energy of more than 11J uniformly distributed over a (7×10) cm2 spot size was achieved using a multichannel spark-gap as the main discharge switch. The discharge was also successfully operated in the switchless mode, yielding a 4.8 J output energy and a 0.9% efficiency. The time-resolved gain measurements provided information on the laser discharge evolution.

Despite the apparent roughness of the method, the use of uncalibrated fluorescent paper can offer enough resolution at low cost for wide aperture excimer lasers if the intensity measurement is carefully performed. See, e.g., Laser Focus, Vol. 25 (August 1989) p. 21
