Semiconductor saturable absorber mirror (SESAM) mode-locked thin disk lasers define the state-of-the-art performance for high average power and high pulse energy femtosecond laser oscillators. To date pulse energies above 30 µJ and average powers above 140 W have been demonstrated. In this paper we review the achievements of mode-locked thin disk lasers in terms of average power and pulse energy. Stable mode locking requires single transverse mode operation even at the highest average power, which is challenging and therefore addressed in more detail. We then summarize our expectations on the main challenges and limitiations for the next generation of mode-locked thin disk laser oscillators with an average power above 500 W and pulse energies in excess of 100 µJ.
半导体可饱和吸收镜（SESAM）锁模薄片激光器代表了高平均功率和高脉冲能量飞秒激光振荡器的当前先进性能。迄今为止，已实现了高于30 μJ的脉冲能量和高于140 W的平均功率。在本文中，我们从平均功率和脉冲能量方面回顾了锁模薄片激光器的成果。即使在最高平均功率下，稳定锁模也需要单横模运行，这具有挑战性，因此将更详细地加以探讨。然后，我们总结了对于下一代平均功率高于500 W且脉冲能量超过100 μJ的锁模薄片激光振荡器主要挑战和限制的预期。
