Optically pumped semiconductor lasers are scalable up to several 10ths of Watts of output power, maintaining
excellent beam quality and high reliability. A further key advantage of the OPS technology is wavelength flexibility:
the accessible wavelength range spans from 915 nm to 1180 nm. Frequency doubling expands this into the blue to
yellow spectral range. The current investigation aims at applications (such as Raman spectroscopy) where ultra-narrow
bandwidth lasers are required. Results of a single frequency green-yellow OPS laser will be presented.
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.
