Abstract:
We report the results of a study of an e-beam pumped vertical-external-cavity surface-emitting laser (VECSEL) based on an InGaAs/AlGaAs heterostructure. Metalorganic chemical vapour deposition (MOCVD) is employed to grow two structures of different design, which contain 10 quantum wells (QWs) and a built-in distributed Bragg reflector (DBR) mirror. Under repetitively pulsed electron-beam excitation (50 Hz, 250 ns), a peak output power of 5.5 W is achieved at a wavelength of 2.5 W and an output power of 2.5 W at 1.013 μm with a total convergence angle no larger than 20 mrad.
