The U.S. Naval Research Laboratory (NRL) has built a 137 J electron beam pumped argon fluoride (ArF) laser operating at 193 nm utilizing the Electra facility. This paper highlights initial ArF oscillator measurements in the context of significant benefits of ArF laser characterization for inertial confinement fusion target performance and development of a kinetics code with predictive capabilities. Other aspects of NRL's ArF laser development program, including large scale electron beam pumped ArF amplifier development and ArF optical transport, are discussed. Initial measurements were made utilizing a quadruple pass oscillator configuration constructed in the Electra facility with a nominal 100 cm² aperture. Laser yields between 80 and 100 J, time-dependent laser intensity, and amplified spontaneous emission (ASE) are reported over a range of gas pressure (0.8–1.4 atmospheres). Higher laser yields, 137 J, were attained in a non-optimized dual ArF oscillator configuration wherein the optical axis was rotated to conform to the measured electron beam deposition in the laser gas mixture.

美国海军研究实验室（NRL）利用Electra设施制造了工作在193 nm的137 J电子束泵浦氟化氩（ArF）激光器。本文在ArF激光表征对惯性约束融合目标性能的显着好处以及开发具有预测能力的动力学代码的背景下，重点介绍了初始ArF振荡器的测量。讨论了NRL的ArF激光器开发计划的其他方面，包括大规模电子束泵浦ArF放大器开发和ArF光学传输。初始测量是使用Electra设施中构造的四通振荡器配置进行的，标称100 cm ²光圈。据报道，在一定气压范围内（0.8-1.4个大气压），激光的产量在80至100 J之间，随时间变化的激光强度和放大的自发发射（ASE）。在非优化的双ArF振荡器配置中，可以获得更高的激光产量137 J，其中光轴旋转以符合在激光气体混合物中测得的电子束沉积。
