Testing results of IAD-Si properties are provided  showing that the amorphous film has great thermal shock resistance. Then  polishing experiments on 100.5m thick IAD-Si layers are accomplished focusing on smoother surface. Surface figure and micro-roughness of the coating after polished reach 0.026 RMS (=0.6328nm) and less than 0.5nm RMS respectively. Moreover  reflectivity of IAD-Si polished surface with reflective films increases higher than 4.5% than that of RB-SiC in 360-1100nm. High reflectivity and desirable thermal property make IAD-Si an attractive coating material for RB-SiC space mirrors. 2009 SPIE.   High-power VCSELs single devices aid 2-D arrays (EI CONFERENCE) 会议论文  OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Liu Y.;  Wang L.;  Wang L.;  Wang L.;  Liu Y. 收藏  |  浏览/下载：14/0  |  提交时间：2013/03/25 The high power bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) and laser arrays emitting at 980 nm are reported. Extensive investigations on size scaling behavior of thermal properties of single devices show limits of attainable output characteristics. The maximum continuous wave (CW) output power at room temperature of single devices with aperture size up to 500 m is as high as 1.95 W. The key characteristics such as maximum output power  wavelength and thermal resistance are discussed. The bottom-emitting arrays of 16 elements and 200 m aperture size of individual elements show output power of CW 1.35 W at room temperature. The far-field angle is below 17 for all driving current  which is very favorable for focusing or collmating optics.
