Self-adaptive compensation of thermal lenses in an end-pumped Nd:YAG laser

摘要

In order to compensate for thermally induced lenses we have recently proposed and successfully demonstrated a new self-adaptive compensation scheme for transversally pumped laser rods. Now we show how this scheme can be simplified and adapted for end-pumped laser rods. The method is demonstrated with an end-pumped Nd:YAG laser and preliminary experimental results are presented.
