High performance 2.2um optically-pumped vertical external-cavity surface-emitting laser

Hopkins, J.M. and Preston, R.D. and MacLean, A.J. and Calvez, S. and Sun, H. and Ng, J. and Steer, M. and Hopkinson, M. and Burns, D. (2007) High performance 2.2um optically-pumped vertical external-cavity surface-emitting laser. Journal of Modern Optics, 54 (12). pp. 1677-1683. ISSN 0950-0340

We report the operation of an optically-pumped vertical-external-cavity surface-emitting laser (OP-VECSEL) oscillating at wavelengths up to 2.2 µm and at output powers greater than 200 mW. This versatile platform provides a broad gain bandwidth, and may be tuned and/or controlled by the addition of elements into the external cavity. Moreover, the nature of the semiconductor structure permits precise engineering of the operating wavelength---not possible with traditional solid state crystalline lasers---and the thin (few microns) pump absorption region, coupled with the external cavity control, permits the mode conversion of a low brightness pump into a high quality TEM00 output.
