Irradiation Effects of Femtosecond Pulses on Refractive Index of Ag-Embedded Nanocomposite Glasses

Chinese Physics Letters 2010年第2期27卷 288-291页

The irradiation effects of femtosecond pulses on Ag-embedded composite glasses fabricated by ion-exchange are investigated using z-scan measurement. Both changes of the refractive index caused by the laser irradiation effect and the third-order optical nonlinearity are observed in the experiment. Taking the change of the linear and nonlinear refractive index into consideration, the fitting results are in agreement with the experimental results.

High Characteristic Temperature 1.3μm InAs/GaAs quantum-dot lasers Grown by Molecular Beam Epitaxy

Chinese Physics Letters 2010年第2期27卷 285-287页

We report the molecular beam epitaxy growth of 1.3 μm InAs/GaAs quantum-dot （Qd） lasers with high characteristic temperature T0. The active region of the lasers consists of five-layer InAs Qds with p-type modulation doping. devices with a stripe width of 4 μm and a cavity length of 1200 μm are fabricated and tested in the pulsed regime under different temperatures. It is found that T0 of the Qd lasers is as high as 532 K in the temperature range from 10°C to 60°C. In addition, the aging test for the lasers under continuous wave operation at 100°C for 72 h shows almost no degradation, indicating the high crystal quality of the devices.

damage Performance of Multilayer Films under Simultaneous Exposure to Multi-Wavelength Pulses

引用

Chinese Physics Letters 2009年第7期26卷 136-138页

作者：周明赵元安凌秀兰李淑红邵建达范正修 Key Laboratory of Material science and Technology for High Power lasers Shanghai Institute of Optics and Fine Mechanics Chinese Academy of Sciences Shanghai 201800 Graduate Universities of Chinese Academy of sciences Beijing 100049

Laser damage performance of multilayer films with combined irradiation of 1ω and 2ω is studied to probe the damage mechanisms during wavelength division. The laser induced damage thresholds （LIdTs） of the samples are obtained and tested with only 2ω with various energy densities of 1ω. different 1ω; polarization directions combined with the 2ω case are also investigated. The result suggests that lw can raise the damage probability of multilayer mirrors when two light wavelengths are present simultaneously; the increasing number of sensitive defects for 2ω can be related to the decline of the LIdTs of the multilayer mirrors.
