Abstract
We describe a tunable broadband mid-IR laser source based on difference-frequency mixing of a femto second Yb:fiber laser oscillator and a Raman-shifted soliton generated with the same laser. The resulting light is tunable over to , with a FWHM bandwidth of and maximum average output power up to . The noise and coherence properties of this source are also investigated and described.
