A Ti:Sapphire-pumped Q-switched waveguide laser was fabricated by fs-laser-writing of two parallel tracks in a bonded Nd:YAG/Cr4+:YAG-crystal. We achieved 1-ns-pulses with an average output power of 300 mW and 300 kHz repetition rate.

We obtained up to 100 mW of cw green output around 541 nm with Tb3+(10%), Na+(10%):CaF2 under pumping with a 2ω-OPSL at 486 nm and a continuous wavelength tuning between 540 nm and 550 nm.

Cubic sesquioxides are excellent host materials for various trivalent rare earth ions emitting in the 1, 2, and 3 µm wavelength range. In this contribution we review the state of the art of Yb3+-, Tm3+-, Ho3+-, and Er3+-doped Lu2O3 lasers emitting in the near- and mid-infrared spectral range.
