This thesis designs a Laser -Produced Plasma(LPP) source with high precision rotation target system
The laser system used as excitation source is a Q-Switched Nb:YAG laser emitting energies from 100mJ to 800mJ at a wavelength of 1. 06um with pulse duration of 8ns (FWHM) and pulse repetition rate of 1Hz.5Hz and 10Hz in combination with two sorts of focusing lenses of 90mm and 240mm focal length. The LPP source developed has short duration of the emission (tens ns)
small light spot(100-200um)
high brightness and high intensity. It can produce considerable amount of Soft X-ray-Vaccum Ultraviolet spectra radiation both line emission and continue emission. In the mean time
the radiative peak wavelength can be adjusted from 13nm to 17nm. The stability and reproducibility of the LPP source is better than4.5%.
