Abstract

Frequency comb technology is continuing to revolutionize many aspects of spectroscopic measurements. For any of the recently demonstrated advanced spectroscopy techniques [1] mid-IR comb sources are highly sought to allow access to the molecular fingerprint region from 2 – 10 μm. Recently mode locked Thulium fiber lasers in conjunction with super continuum generation have been suggested for this application [2] and self-referenced carrier-envelope-offset frequency (f_ceo) detection has been demonstrated with a Tm fiber laser using supercontinuum generation in PPLN waveguides [3].
