Broadband 1-GHz mid-infrared frequency comb Light: Science

WebThe generation of programmable complex femtosecond pulses in the mid infrared (3–10 μm) with high precision is reported. Designed pulse shapes in the near infrared (1–1.6 μm) are transferred to the mid infrared via difference-frequency mixing with a second infrared pulse spectrally narrowed in a zero-dispersion compressor. In particular, pulse … Web12 dec. 2012 · We have presented a mid-infrared quantum-cascade-laser free-running optical frequency comb covering 60 cm −1 (308 nm) at a centre wavenumber of 1,430 … compact rv water hose
