Abstract

A nanosecond pulse discharge circuit is developed and used to enhance the optical emission of laser plasma. An intense discharge spark was observed with a peak discharge current of 1.9kA and a peak power of 6.5MW. The main electric energy deposition only lasted for 40ns. An intense optical emission was observed. The line intensity of plasma emission was greatly increased along with an improved signal-to-noise ratio, in comparison with that using a microsecond pulse discharge circuit. From the measured spectra, electron temperature and electron number density were estimated. The mechanism of the optical emission enhancement was briefly discussed.
