High power and high power conversion efficiency are extremely important in diode lasers  and they could lead to new applications where space  weight and electrical power are critical. High efficiency devices generate less waste heat  which means less strain on the cooling system and more tolerance to thermal conductivity variation  a lower junction temperature and longer lifetimes. Diode lasers with Al-free materials have superior power conversion efficiency compared with conventional AlGaAs/GaAs devices because of their lower differential series resistance and higher thermal conductivity. 808nm GaAsP/GalnP broad-waveguide emitting diode laser bars with 1mm cavity length have been fabricated. The peak power can reach to 100.9W at 106.5A at quasicontinuous wave operation (200s  1000Hz). The maximum power conversion efficiency is 57.38%. Based on these high power laser bars  we fabricate a 1 3 arrays  the maximum power is 64.3 W in continuous wave mode when the current is 25.0A. And the threshold current is 5.9A  the slope efficiency is 3.37 W/A. 2008 SPIE.   High power 1064nm laser diode array and measuring chip temperature based on emitting spectra (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 X.;  Wang L.;  Wang L.;  Wang L.;  Wang Y. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 High power laser diode array with an emission wavelength of 1064nm is presented. The epitaxial structure is an InGaAs/GaAsP strained-compensated single-quantum well structure. The modules CW output power can reach to 56.5W at current of 80A. Because the heat capacity of st rather shorter pulse duration and lower duty cycle  the average driving power in the laser chip is quite low  so the heating effect cemiconductor laser is very small  using pulse injection can reduce temperature rising significantly. Aould be neglected. The definite relation between lasing wavelength and chip temperature is developed. The temperature drift coefficient is 0. 45nm/K 2008 SPIE.   Landslide and Rockfall Distribution by Reservior of Stepped Hydropower Station 期刊论文  OAI收割 Wuhan University Journal of Natural Sciences, 2006, 卷号: 11, 期号: 4, 页码: 801-805 作者:  Li Yong（李勇）;  Cheng Genwei（程根伟） 收藏  |  浏览/下载：38/0  |  提交时间：2010/11/11 lower reach of Jinsha River  reservoir area  landslide and rockfall  distribution characteristics and laws
