| Abstract: | A 1.06μm,10ns Nd:YAG laser was used to irradiate titanium alloy target. The plasma emission spectra of titanium in the wavelength range of 438nm to 448nm and in the time delay range of 10ns to 170ns were detected by an optical multiple analyzer(OMAII) system. The spectra were analyzed. According to the intensity of two separated titanium atom spectral lines, the electron temperature of the plasma at different time delays were evaluated. |
