Abstract

The use of resistive plastic materials in the trigger circuit of double‐discharge lasers has proven excellent in producing increased trigger current values, and in achieving successfull operation of lasers with large (up to 7.6 cm) electrode separations. Small signal gain values of 0.04 cm⁻¹ have been obtained in a He:N₂:CO₂=50:20:30 gas mixture. Furthermore, the dielectric constant and resistivity of the plastic materials can be selected for pulse shaping in the trigger circuit. A trigger assembly has been designed in a simple and rugged unit, suitable for cascaded operation in long laser amplifier systems.
