【摘要】 采用侧面紫外火花隙自动预电离代替小极上小孔预电离，使放电泵浦氟化氪激光器的主放电均匀性大为改善。输出激光能量由１４０ｍＪ提高到２５０ｍＪ，增益区光能密度为２．３Ｊ／１，同时电极寿命和气体寿命也大为提高。更多还原

【Abstract】 A discharge-pumped KrF laser is constructed.Preionization holes in the electrode surface are replaced by two raws of pins on the side of the electrode for ultraviolet autopreionlzation, resulting in a considerable improvement of main discharge uniformity and an increase of energy depletion. Laser output ranges from l40mJ to 25OmJ with the energy efficiency of 0.8%, and specific energy of2.3J/1.In addition,the lifetime of the gas and electrodes is also increased.更多还原
