The performance of optically pumped semiconductor vertical external-cavity surface emitting laser(OPS-VECSEL)is influenced by many parameters
so the theoretical analysis and simulation are very important.We constructed a 980 nm optically pumped semiconductor vertical external-cavity surface emitting laser(OPS-VECSEL)with active region of In

system pumped by 808 nm laser diode module.Employing the PICS3D software
the characteristic parameters of OPS-VECSEL were calculated.The performances of device especially the threshold and the optical-optical conversion efficiency were influenced by the chip radius
the number of quantum well and the reflectivity of external-cavity mirror.Calculation and analysis show that the chip radius affect optical-optical conversion efficiency.The output power and optical-optical conversion efficiency are influenced by the number of quantum wells and the reflectivity of external-cavity mirror.Thus we should design and grow the laser structure according to the need.
