Abstract: High pressure argon gass from 1 to 200 atm. is irradiated by a Q-switched ruby laser with the maximum power of 40MW and a half width of 30ns. A dense hot plasma is produced in high pressure argon gass, and a radiation emitted from the laser plasma is spectroscopically analysed. The radiation has line spectrum of Ar I and Ar II with continuous spectrum. Improving the electric power source circuit, the laser output power is stabilized and the scatter in measured values is reduced. The plasma temperature is determined from the line intensity ratio of Ar II over the wide pressure range up ot 100 atm. The plasma temperature increases with increase of pressure, but the dependence of the temperature on pressure is weak. The plasma temperature obtained in this work is order of 10eV, which is reasonable from the result in other paper at atmospheric pressure. The plasma temperature is also determined from continuous spectrum and energy balance.
