Abstract: Molecular precision spectroscopy opens new perspectives on tests of fundamental laws of physics and of fundamental constants variation [1]. The mid infrared (IR) is a key region for molecular spectroscopy, and the efforts towards the development of versatile, spectrally pure, and tunable coherent sources in this region have been constantly growing in the last decade. A convenient way to generate a mid-IR tunable source for precision spectroscopy is difference-frequency generation (DFG) in a nonlinear crystal starting from two visible or near-infrared sources. Cs-traceability can be achieved by locking the pump and signal lasers to an optical frequency comb referenced to the primary frequency standard. © 2017 IEEE
