Abstract

The HCP(Hypocycloidal Pinch) device for plasma focus was modified for a pumping source of the dye laser, and the spectral distribution and time behavior of its light pulses were investigated by using a UV spectrometer, 70 MHz CRO and Si-PIN photodiode detector. An array of multiple stages of HCP and narrower electrode gaps were chosen in order to make a more uniform discharge along the HCP axis. The possible spectral range for the pumping of dye laser is 360-620nm, when the HCP is operated at 5-8kv of apllied voltage and 50-150Torr of Ar fill gas pressure. The rise-time and FWHM of light pulses from the HCP are 5us and 30-50us respectively when it is operated under the same conditions as above.
