Abstract

We report on the generation of high energy, high power pulses in a tabletop diode-pumped Tm:YLF-based laser system, which delivers amplified pulse energies up to 108 J, as well as GW peak power performance when seeded with nanosecond duration pulses. Furthermore, the high power and efficiency capabilities of operating Tm:YLF in the multi-pulse extraction (MPE) regime were explored by seeding the experimental setup with a multi-kHz burst of pulses exhibiting a low individual pulse fluence, resulting in a 3.6 kW average power train of multi-joule-level pulses with an optical-to-optical efficiency of 19%.

摘要

我们报道了在基于桌面二极管泵浦Tm:YLF的激光系统中产生高能量、高功率脉冲的情况。该系统可提供高达108 J的放大脉冲能量，并且在注入纳秒持续时间的脉冲时具有GW级的峰值功率性能。此外，通过向实验装置注入多kHz的低单脉冲能量密度脉冲串，探索了Tm:YLF在多脉冲提取（MPE）模式下的高功率和高效率能力，从而得到了平均功率为3.6 kW的多焦耳级脉冲序列，光光效率为19%。
