    Abstract

    We have demonstrated the highest reported output power from a mid-IR ZGP OPO. The laser is a cascaded hybrid system consisting of a thulium fibre laser, Ho:YAG solid state laser and a Zinc Germanium Phosphide parametric oscillator. The system produces 27 W of output power in the 3-5 μm wavelength range with an M2=4.0 when operating in a repetitively q-switched mode, and a modulated peak output power of 99W at a reduced duty cycle of 25%.
