920 nm optically pumped semiconductor vertical external-cavity surface emitting laser (OPS-VECSEL) has an important application in laser display. We constructed and optimized a 920 nm OPS-VECSEL with active region of In0.09Ga0.91As quantum well (QW) system pumped by 808 nm laser diode module. By the finite element method  self-consistent solutions of the semiconductor electronic and optical equations are realized to calculate the characteristics parameters of OPS-VECSEL. The performances of device especially the mode  the threshold and the optical-optical translation efficiency were analyzed by dealing with different number of QWs (1  2 and 3) in one period  QW depth  barrier width  the component and dimension of the non-absorption layer. We chose an improved structure of them. On this basis  we ameliorated the number of QW periods and the simulation showed that in order to obtain high performance device  the choice of the number of QW periods must be cautious.

Operating principle of laser beam-riding guidance was set forth. Based on the principle of spatial frequency-encoding  experimental results demonstrated that the receiver can receive correctly the encoded signal and can decode the signal  an optimum laser encoding mode was designed  measurement for the missdistance is feasible and all the performance parameters satisfy the demand. (2012) Trans Tech Publications  which can transfer continuous laser into pulse laser that represents different position information. Then the mathematic model of deviation from target is built  Switzerland.  a modified encoding pattern was presented  which is composed of two light paths crossed 90. Azimuth information of target is given in orthogonal coordinate system and deviation from target is linearity. As well as  characteristic distribution of spatial laser field is analyzed. Corresponding decoding mode was presented  by testing in 2 kilometers outdoor

Theoretical analysis and experimental study were carried out on the high-power CO2 laser disturbance to long-wave infrared (LWIR) HgCdTe detector in this paper. Based on the practical parameters of experiment  the theoretical model of temperature-rise is adopted to calculate the variation of the temperature with the time and the power of laser for laser irradiation on the detector. After that  the damage threshold is 110W/cm2. This experimental phenomenon well agrees with the results predicted by the theoretical calculation. The conclusions have a certain reference value for the laser defense of detector. 2011 IEEE.  the high-power laser damage mechanism to LWIR detector is discussed  and compares with the experimental results of laser irradiation the detector on the distance of 15km. The theoretical and experimental results demonstrate that the interference threshold of the detector is 20.5W/cm 2
