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.

In high precise surface testing  temperature stability and uniformity are of paramount importance to the high accuracy of test results. Micro-temperature variation and temperature gradients not only cause the change of the air refractive index and lead to the optical path variation in interferometer cavity  but also result in deformation of the tested surface itself  which always brings about errors to the test results. Temperature effects on the interferometer cavity and the tested surface are analyzed from the axial and radial directions in this letter. Temperature model of the interferometer cavity and the tested lens are established and quantitative calculations and diagram of test results versus temperature and lens dimension are provided. It shows that temperature gradients effect increase with the length of the interferometer and the dimension of the tested lens. The interferometer cavity is mainly affected by radial temperature gradients while the tested lens is mainly affected by the axial temperature gradients. 2010 Copyright SPIE - The International Society for Optical Engineering.
