Laser sources around 2 | im and non-linear converters covering the mid-infrared (Mid-IR) spectral range are important for a large variety of applications like in environmental sensing, detection and ranging, optical free-space communication, optical countermeasures, medical treatments and surgery, and fundamental physics research. Especially recent developments in two-micron pulsed thulium and thulium-holmium doped fiber lasers allow for significant average-power and energy scaling of mid-IR OPOs based on ZnGeP2 or OP-GaAs conversion crystals thereby broadening the scope of various applications. The presentation gives an overview of fundamental concepts, recent achievements as well as novel results in the field.
