Schwarzbäck, M. Eichfelder, W.-M. Schulz, R. Roßbach, M. Jetter, P. Michler] We present a vertical external cavity surface-emitting laser system based on a multi-quantum-well structure with 20 compressively strained GaInP quantum wells for an operation wavelength of around 665nm with a monolithic integrated distributed Bragg reflector. With the help of an intra-cavity diamond heatspreader the laser operates in continuous-wave mode. Operation with a TEM00 Gaussian beam profile and a beam propagation factor of M 2≤1.05 is shown as well as a high resolution spectrum of the laser line, which shows the etalon effect of the diamond. The laser can be operated at a maximum output power exceeding 1.2W with a slope efficiency of η diff=18%. At maximum output power the wavelength of the laser resonance is at 670nm, which is shortest reported until now at powers exceeding 1W. By rotating a birefringent filter in an extended folded cavity arrangement a wavelength tuning of 21nm was attained. Springer-Verlag, 2010 Schwarzbäck T.
