The authors demonstrate a free-space optical data link over 350m using a Peltier-cooled 9.3 mum quantum cascade laser operating at a duty cycle of almost 50%. On the emitter side, a Cie lens was used for beam collimation and a nat mirror for beam steering, while on the receiver side, a fast roam-temperature HgCdTe detector in combination with a phi = 16cm mirror telescope detected the incoming signal. Short pulses at a maximum repetition rate of 330MHz were successfully transmitted. The signal-to-noise ratio of the measurement was limited by the power equivalent noise of the detector.
