Abstract

This paper describes part of the EUREKA Eurolaser project EU213, to build an excimer laser. The emphasis is on control and monitoring systems. The performance of a test-bed laser built at Salford will be described. In the design discussed, two voltage components are generated separately and combined at the laser head to form a pumping pulse. A "magnetic switch" is used to isolate the two parts of the transmission line'. A theoretical analysis of the sustainer section of the line has been carried out and compared with measurements made using a dummy load in place of the laser head. A control system is discussed that is being developed to monitor the shape of each laser pulse at a high repetition rate. The control system is designed to protect the laser from damage. The construction of various conventional probes, and the progress towards various fibre probes will be reported with emphasis on measuring fast current pulses on the various parts of the line.
