Effect of delay time between pre-pulse and main pulse on single-pass and double-pass amplification of 46.9 nm laser
《Chinese Optics Letters》2023年第5期104-109,共6页赵东迪 赵永蓬 崔怀愈 安博 李镭 白云松 
supported by the National Natural Science Foundation of China(Nos.61875045 and 62005066)。
In this paper,the influence of the delay time between the pre-pulse and the main pulse on the double-pass amplified 46.9 nm laser was studied for the first time,to the best of our knowledge,by using a high-precision p...

Double-pass grating imaging spectrometer
《Chinese Optics Letters》2019年第1期43-46,共4页Xin Meng Zhongming Yang Jinyu Du Guobin Fan 
partially supported by the Natural Science Foundation of Anhui Province(No.1808085QF201);the China Postdoctoral Science Foundation(No.2018M630773);the Fundamental Research Funds of Shandong University(No.11170077614092)
A double-pass grating imaging spectrometer is proposed and demonstrated. The traditional entrance slit is replaced by a middle reflective slit, which is used as a spectral filter rather than a spatial filter. The ligh...

Wide-band double-pass discrete Raman amplifier with reflection of signals and pumps被引量：1
《Chinese Optics Letters》2004年第8期480-482,共3页王著元 崔一平 
This work was supported by the National Science Foun- dation of China for Distinguished Young Scholars under Grant No. 60125513.
A wide-band (1530-1610 nm) and high efficient double-pass discrete Raman amplifier is reported. In this Raman amplifier, by using a one-end gilded fiber as the broadband reflector, signals and multi-pump are both refl...
