Add-on: OPA, SHG, THG, MIR

Frequency combs in the molecular finger-print region have enabled applications in metrology, spectroscopy and medicine. All these applications benefit from higher average powers that allow for faster acquisition rates and an improved signal-to-noise ratio. This extension complements the compact 50fs-thulium-doped ultrafast fiber laser system and provides a high-power frequency comb in the mid-IR.
The ultrafast mid-IR pulses are achieved through intra-pulse difference-frequency generation, which guarantees passive carrier-envelope-offset stability. The complete frequency-comb nature of the source can be achieved by controlling and stabilizing the fundamental pulse-repetition frequency of the driving laser.
