Paper Abstract

Diode pumped frequency doubled Optically Pumped Semiconductor lasers (OPS), has proven to be a reliable source of laser radiation in the blue and blue-green spectral range between 460 nm and 505 nm. One of the major advantages of using semiconductors as gain medium is the possibility to tailor the wavelength of the semiconductor material by means of band gap engineering. Here we report about new OPS material enabling the wavelength region between 1090 nm and 1160 nm which allows the realization of frequency doubled lasers between 545 nm and 580 nm. Laser results up to several Watts in the yellow spectral range as well as efficiency and lifetime data will be presented.
