近年来，人们对光泵分子激光器越来越注意。文献[3]中报导了用新的激活介质14ΝH3获得峰值功率为5千瓦、效率0.3%、波长为λ=12.81微米的振荡。继文献[3]之后，马上又出现了好些工作，报导了用单光子泵浦时在新的波段——12.08及11.46微米、 12.28微米——获得的振荡，在用两台CO2激光器进行双光子泵浦时在6~35微米波段内的许多波长上也获得了振荡。

We build up a common-path optical coherence tomography (OCT) system using reflected light of sample surface as reference light. As the zero path length reference point has nothing to do with the distance between probe and organ, it can be utilized in endo
Video-rate multimodal multiphoton imaging and three-dimensional characterization of cellular dynamic
To date, numerous studies have been performed to elucidate the complex cellular dynamics in skin diseases, but few have attempted to characterize these cellular events under conditions similar to the native environment. To address this challenge, a three-
自上次在莫斯科召开欧洲激光与物质相互作用会议以来，已有八年了。那时候，不是按排得这样好的会议，西方参加的人是不多的;在公开发表的文献中，越来越强调产生高度压缩的DT靶(其密度远远超过通常的固体密度)对于激光核聚变的实际重要性;但当时可供利用的激光技术仍然比较原始。

We propose a new subdivision technique directly subdividing the grating stripe by using complementary metal-oxide semiconductor (CMOS) microscopic imaging system combined with image processing. The corresponding optical system, subdivision principle, and
