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.   Optical thin films for high power LD-pumped Nd:YVO4 457nm blue laser (EI CONFERENCE) 会议论文  OAI收割 ICO20: Optical Design and Fabrication, August 21, 2005 - August 26, 2005, Changchun, China Bu Y.; Zheng Q.; Xue Q.; Qian L. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 The expanding field of LD-pumped solid state lasers forms an extraordinary challenge for developing the optical coatings. Optical thin films for LD-pumped Nd:YVO4/LBO blue laser at 457nm was presented in this paper based on lower gain laser line action theory  including spectral beam dividers and doubling antireflecting multilayer coatings. To achieve 914nm laser action and 457nm blue light high output power  the coating specifications of laser resonator was analyzed. The transmittance/reflectance spectrum request was effectively separated by adopting high tuned radio stack  simultaneously the spectrum request was reasonably distributed on the two resonator facet reflectivity for restrain the other laser lines such as1064nm and1342nm. The dielectric high reflective laser mirror and antireflecting coatings for 457nm laser were manufactured by double ion beam sputtering technique  which is controlled by a time-power monitoring. Using type-I critical phase-matching LBO crystal  457nm blue laser is obtained by 914nm intracavity frequency doubling. The maximum laser output power of 1.5W is obtained when incident pump laser of 15W is used.   Theoretical study of the pump light absorption inside a three-level solid state laser medium 期刊论文  OAI收割 ACTA PHYSICA SINICA, 2005, 卷号: 54, 页码: 1587-1592 作者:  Qin, H;  Fu, RL;  Gao, HY;  Liu, J;  Shi, XG   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/05/31 pump  laser medium  photon transport equation  light absorption   散射中心型超分辨近场结构的非线性光学特性研究进展 期刊论文  OAI收割 激光与光电子学进展, 2005, 卷号: 42, 期号: 2, 页码: 23, 29 瞿青玲; 王阳; 徐文东; 干福熹 收藏  |  浏览/下载：1427/203  |  提交时间：2009/09/22 散射中心  light-scattering center super-resolution near-field structure (LSC-Super-RENS) nonlinearity  近场  Z-SCAN  超分辨  pump-probe technique  掩模  非线性光学  特性研究  光学特性  非线性响应  物理机制  纳米尺度
