【Abstract】 A 10J level of optically pumping XeF（C-A）laser has been developed which can be operated on repetition mode.The laser system consists of a laser device and a XeF₂ generator.The laser chamber is 167cm in length,20cm in height and 13cm in width with an aperture of 5 cm×5 cm.The irradiation from a sectioned surface discharge is used to photolysis XeF₂.Lasing is investigated by employing a stable resonator with the length of 210 cm and the output coupling of 10%.The active mixed gases with XeF₂ concentration of（0．6～1．2）×10¹⁷cm^-3can be obtained from XeF₂ generator.The lasing experiments have been performed and the laser can be operated in the repetitive rate of 0．2～1Hz.At present,the maximum output energy of first pulse is 18．7J and the total conversion efficiency of 2．5‰ is obtained.The duration of laser pulse is about 1μs.更多还原
