Characteristic study on optical pump source by transverse surface discharge

An optical source used to pump XeF(C-A) laser is introduced. The discharge breakdown property, the current as a function of charge voltage in different gas, the discharge homogeneity and the effect of different gas composition on the discharge radiation have been experimentally studied. The discharge breakdown time, peak current as a function of charge voltage and buffer gas are obtained. The methods of increasing the discharge homogeneity are analysed. The time-integrated spectra of discharge radiation under different experimental conditions are also obtained. By analysing radiation spectra, the optimum experimental condition of photo-dissociation XeF2 is defined. The radiation intensity on the XUV region arrives the maximum value in case of pAr : pN2 =1:1.
