High-power solid state laser system at 589 nmAxel Friedenauer, •Manfred Hager, Bernhard Ernstberger, and Wilhelm Kaenders — TOPTICA Photonics AG, Gräfelfing, Germany

A novel scheme is presented which allows for generating high-power diffraction-limited laser radiation in the yellow spectral region. An extended cavity diode laser (ECDL) emitting at a wavelength of 1178 nm serves as a master oscillator and provides seed signals for two PM fibre Raman amplifiers. The output of these amplifiers is coherently combined and resonantly frequency-doubled to obtain more than 30 W of narrow-band tunable output power to resonantly address the sodium D2 transition at 589 nm.

The results have been obtained in collaboration with MPBC and ESO.
