由于热透镜引起的失准不稳定性引起的薄磁盘laser缩放极限
Thin-disk laser scaling limit due to thermal-lens induced misalignment instability
摘要：
我们提出了一个障碍，在薄盘激光器的功率缩放与自驱动增长的失调，由于热透镜效应。这种自驱动生长是由于激光本征模偏离光轴而引起的光盘处的光学相位差的变化而引起的。我们发现了一个标准的基础上，这种现象的简化模型，可以应用于设计激光谐振腔不敏感的这种影响。此外，我们提出了几个谐振器架构，不受这种影响。
英文摘要：
We present an obstacle in power scaling of thin-disk lasers related with self-driven growth of misalignment due to thermal lens effects. This self-driven growth arises from the changes of the optical phase difference at the disk caused by the excursion of the laser eigen-mode from the optical axis. We found a criterion based on a simplified model of this phenomenon which can be applied to design laser resonators insensitive to this effect. Moreover, we propose several resonator architectures which are not affected by this effect.
