Ultrafast tunable mid IR source

We report on a Laser source, emitting in the mid-IR spectral range. A mode-locked Nd: YVO Laser is used as a pump Laser, followed by two nonlinear frequency conversion steps (OPG, DFG). The broad-band output beam is tunable between 9 μm and 13 μm, with average powers up to 10 mW. Further extension of the tuning range is possible.
