This work gives the basic operation function of semiconductor disk laser  and analyses the heat effect by the experimentally measured photoluminescence spectrum of the laser chip at different pump power and different temperature. We can see that: with increasing pump power  the thermal effects of the gain material becomes seriously and causes the saturation of carrier lifetime  so the electron-hole pair created in the absorbtion layer have no enough time to rate to one of the wells  and the non-radiative recombination happens in the barrier. When the thermal effects becomes stronger  the chip will not lasing. This phenomenon is from the smaller energy offset between barrier and quantum well. We optimize the original structure design and experimental technology. A non-absorbing AlGaAs layer who is transparent to the pumping and laser wavelength is added to confine the carriers in the quantum wells. At the same time a DBR with double reflecting band is induced to improve the absorbing efficiency of the pumping light. The single QW is replaced by the three narrow QWs  This three QWs structure can add the quantum state of QW  increase the recombination probability of carriers in the QWs and reduce the heat effect. The chemical etch equipment is also improved to control the surface unevenness to be within 50 nm.   Effect of lithium-potassium mixed alkali on spectroscopic properties of Er3+-doped aluminophosphate glasses 期刊论文  OAI收割 chin. phys., 2007, 卷号: 16, 期号: 6, 页码: 1736, 1742 房永征; 廖梅松; 胡丽丽 收藏  |  浏览/下载：1472/183  |  提交时间：2009/09/24 non-crystalline materials  mixed alkali  radiative lifetime  Judd-Ofelt theory   Dependence of the spontaneous emission rates of emitters on the refractive index of the surrounding media 期刊论文  OAI收割 JOURNAL OF ALLOYS AND COMPOUNDS, 2006, 卷号: 418, 页码: 213-216 作者:  Duan, Chang-Kui;  Reid, Michael F.   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/05/31 local-field effect  radiative lifetime  virtual-cavity model  real-cavity model  refractive index   Local field effects on the radiative lifetimes of Ce3+ in different hosts 期刊论文  OAI收割 CURRENT APPLIED PHYSICS, 2006, 卷号: 6, 页码: 348-350 作者:  Duan, CK;  Reid, MF   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/05/31 local-field effect  radiative lifetime  Ce3+  5d-4f transition   Spectroscopic investigations of Er3+ doped Bi2O 3 -B2O3 -SiO2 glass (EI CONFERENCE) 会议论文  OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Chen B.;  Wang X.;  Wang X.;  Wang X.;  Wang C. 收藏  |  浏览/下载：67/0  |  提交时间：2013/03/25 From the optical absorption measurements  the Judd-Ofelt parameters were computed using Judd-Ofelt theory. According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime  the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host  the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.   Local field effects on the radiative lifetime of emitters in surrounding media: Virtual- or real-cavity model? 期刊论文  OAI收割 PHYSICS LETTERS A, 2005, 卷号: 343, 页码: 474-480 作者:  Duan, CK;  Reid, MF;  Wang, ZQ   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/05/31 local-field effect  radiative lifetime  virtual-cavity model  real-cavity model  refractive index   Production of electron neutrinos at nuclear power reactors and the prospects for neutrino physics 期刊论文  OAI收割 PHYSICAL REVIEW D, 2005, 卷号: 72, 期号: 1 作者:  TEXONO Collaboration 收藏  |  浏览/下载：21/0  |  提交时间：2015/12/02 RADIATIVE-LIFETIME  MAGNETIC-MOMENT  BETA  SPECTROSCOPY  SCATTERING  SPECTRUM  DECAYS  LIMITS  BEAMS
