In this technology  semiconductor laser are cleaved in the air  and the surface oxide layer is removed with a low energy ion source  flowed immediately by coating the facet with thin ZnSe layer of 20 nm. The function of this layer is to protect semiconductor laser facet  and prevent impurity particles diffusing to the facet. Finally the facet is coated with oxidative optical film. The test results show that the output power of the semiconductor laser with the ZnSe coated layer is 13% higher than that of the Si coated layer  and 47% higher than that of the oxide coated film. The device coated oxide film is damaged when current is 4.5 A  and the device coated with Si layer is damaged when current is 5.5 A  the final failed device is coated with ZnSe layer. In conclusion  the method of coating ZnSe layer on the semiconductor laser facet can prevent effectively the catastrophic optical mirror damage  and increase the output power of semiconductor lasers. 2010 IEEE.   Energy transfer processes on both Er+ ion concentration and excitation densities in Yb3+-Er3+ codoped LaF3 matrix (EI CONFERENCE) 会议论文  OAI收割 作者:  Zhang J.;  Wang Y.;  Wang Y.;  Wang Y.;  Zhang J. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 The effects of both Er3+ ion concentration and excited density upon frequency upconversion fluorescence emissions in Er3+/Yb 3+-codoped LaF3 powder are investigated. The results reveal that a higher Er3+ concentration can induce not only upconversion emission enhancements but also the changes among the relative intensities of the 407  519  539 and 651 nm radiation transitions as the samples are excited within the ranges of 20 to 700 mW with 978 nm laser diode (LD) as an excitation source. The changes are described by a schematic level model with the cross-relaxation processes between Er3+ ions and a series of dynamic equations that take into account the population of temperature dependent in Er3+. 2006 Elsevier B.V.

We use Bragg fiber grating as the resonance cavity of fiber laser and 970nm LD as pumping source  pump the Yb-doped double cladding fiber with circular inner-cladding. We realized 7.5 W single-mode laser output  central wavelength of 1080nm  FWHM of 0.11 nm under the pump power of 11.8W. Maxim conversion efficiency is 63.5 % and slope efficiency of 46.4%.   Results of the first on-line experiment of the laser ion source 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2002, 卷号: 26, 期号: 2, 页码: 134-140 作者:  Yang, YF;  Zhao, ZZ;  Zheng, ZM;  Zu, KL;  Wang, XD   |  收藏  |  浏览/下载：26/0  |  提交时间：2010/10/29 laser ion source  on-line isotope separator  element selectivity  isomer   Measurement of the transmission efficiency of He-jet laser time-of-flight mass spectrometer 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 1999, 卷号: 23, 页码: 244-249 作者:  Cheng, HX;  Pang, WN;  Shang, RC;  Zhang, W;  Ta, L   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/05/31 laser ion source  He-jet  time-of-flight  transmission efficiency
