Abstract

This paper describes a simple intrinsic optical fiber current sensor, based on the Faraday effect, which has been specially designed for use in a high average power discharge-pumped excimer laser. The sensor built at Salford has a design bandwidth of 200 MHz, and has been demonstrated in action on the pulse-forming line of an excimer laser pulse power circuit. Its performance is compared with that of a low-inductance current-viewing resistor in the same circuit.
