Responses of the modified TOFs (MTOFs) to methylene blue (MB) solution and surrounding refractive index (RI) have been compared. The higher-order modes are effectively filtered by the silica nanospheres  which is visualized by the interferometric output spectrum of the MTOF. The higher-order mode filtering makes the MTOF respond to MB solution with reduced sensitivity  which endows the MTOF with the potential for distinguishing the RI property from the absorption property of the molecules under detection. 2013 Optical Society of America.   A novel bottom-emitting vcsel's one-dimension array (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Wang L.;  Wang L.;  Wang L.;  Liu Y.;  Liu Y. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 A novel 980nm bottom-emitting VCSELs array with high power density and good beam property of Gaussian far-field distribution is reported. This array is composed of 5 symmetrically-arranged elements of 200m  150m and 100m-diameter  with the center spacings of 300m and 250m respectively. The maximum power is 880mW at a current of 4A  corresponding to lKW/cm2 average optical power density. The differential resistance is 0.09 with a threshold of 0.56A. The novel array is compared with a 300m-aperture-size single device and a 44 2-D array with 50m element aperture size and 250m centre spacing. The three devices have the same lasing area. The conclusion is that the novel array is better in the property of output power  threshold current  lasing spectra  far-field distribution etc. 2008 SPIE.   Acceleration of electron bunches by intense laser pulse in vacuum 期刊论文  OAI收割 NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT, 2003, 卷号: 508, 页码: 211-219 作者:  Hua, JF;  Ho, YK;  Lin, YZ;  Cao, N   |  收藏  |  浏览/下载：28/0  |  提交时间：2018/05/31 laser acceleration  output property  ultra-intense laser  electron bunch
