论文摘要
我们报告带有带锁的sESAM模式锁的HO：CALGO散装激光器，其平均功率为8.7 W，光向效率为38.2％，中心波长为2.1 UM。在此功率水平上，散装激光器以84.4 MHz的重复速率生成持续时间为369 FS的脉冲，对应于103 NJ的脉冲能量，峰值功率为246 kW。据我们所知，这是直接从2-3 um波长区域中直接产生的平均功率和脉冲能量。我们目前的结果表明，HO：Calgo是2 UM飞秒激光器平均功率缩放的竞争候选者。
We report on an in-band pumped SESAM mode-locked Ho:CALGO bulk laser with a record-high average power of 8.7 W and an optical-to-optical efficiency of 38.2% at a central wavelength of 2.1 um. At this power level, the bulk laser generates pulses with a duration of 369 fs at 84.4-MHz repetition rate, corresponding to a pulse energy of 103 nJ and a peak power of 246 kW. To the best of our knowledge, this is the highest average power and pulse energy directly generated from a mode-locked bulk laser in the 2-3 um wavelength region. Our current results indicate that Ho:CALGO is a competitive candidate for average power scaling of 2 um femtosecond lasers.
