Under the incentive of the civil - market demanding such as laser material processing and the military - market demanding such as a new generation of laser weapon candidate and icf, diode - pumped solid laser ( dpsl ) develops rapidly worldwide. as an important application, diode - pumped intracavity - frequency - doubled laser is attached much importance in recent years, but there still remain many problems unresolved completely. in this paper, i have given some abecedarian study results on some of these problems theoretically and experimentally
因工業激光材料加工等民用市場的需求以及慣性約束聚變和作為新一代激光武器候選器件等軍方需求的推動,國際上高功率二極體泵浦固體激光器( dpsl )的研究
