Structural Improvement of 920 nm Optically Pumped Semiconductor Vertical External-cavity Surface Emitting Laser (OPS-VECSEL) Xuemei Liang1,a, Li Qin2,b, Yongqiang Ning2,c, Yun Liu2,d,Lijun Wang2,e 1Jilin Agricultural University, China 2Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences，China aliangxuemei1026@hotmail.com, b qinl@ciomp.ac.cn, c ningyq@ciomp.ac.cn, dhx5252@sohu.com,e wanglj@ciomp.ac.cn Keywords: semiconductor lasers; structural improvement; finite element; vertical external-cavity surface emitting laser; optically pumped Abstract. 920 nm OPS-VECSEL has an important application in laser display.
(6) is the material refractive index of the active region, L is the laser cavity length, R1 and R2 are reflectivity of the DBR and external cavity mirror, Np is the photon amount in the cavity of the mode p.
The output characteristics of these devices were calculated by building up the material storage and setting optical power density, center wavelength, threshold, scan step size and calculation precision, Results and analysis 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 (as shown in Fig.2) [5].

Introduction The belt conveyor is widely used in the transport of various types of material and is exposed to the most varied ambient conditions, weather and environment.
According to the type of transported materials, the conveyor belts are classified as belts of class 2 (grain size between 50 and 100 mm, moderate bulk weight) and 3 (grain size between 150 and 400 mm, sorted material, high bulk weight).
Fig. 2 Empirical and calculated values of the lifetime Summary Material flow is realized by two basic groups of elements: passive and active.
