Measurement of Gain and Device Performance of a 1050-nm Vertical External Cavity Surface Emitting Laser

In this paper, we measure and analyze the pump power and wavelength dependent gain of an optically pumped infrared 1050-nm vertical external-cavity surface-emitting laser vertical external-cavity surface-emitting laser (VECSEL) developed for an application as a frequency doubled green laser in mobile projectors. Increasing the reflectivity of the chip… (More)
