Abstract

A capillary discharge 46.9 nm Ne-like Ar laser is achieved with peak current of 20–23 kA. The variation of laser pulse duration with initial Ar pressure and rise-time of main current is reported. Measurements show that the laser pulse durations slightly increase with the increased pressure and increased rise-time of current. A comparison of the experimental results with the calculation of snow-plow model indicates that the increase of laser pulse duration is the result of decreased Z-pinch velocity at the pinch time when the radius of plasma is minimal.
