| Outline of Final Research Achievements |
Generating conditions of laser sustained plasma (LSP) using 1kW class diode laser were investigated. For 1 MPa xenon gas, the LSP could be generated at the laser power higher than 526 W. The fractional absorption of the laser power increased with the increase in the laser power. As a result of emission spectroscopy, the LSP temperature was 6200 K at maximum. For argon gas, the LSP could not be generated even at the pressure of 5 MPa. Then, higher pressure or higher laser power are necessary to generate the argon LSP.
