Abstract

In this Letter, we report an octave-spanning mid-infrared (MIR) comb generation with a difference frequency generation (DFG) approach optimized for aperiodically poled ${\rm Mg}:{{\rm LiNbO}_3}$ and nonlinear spectral broadening. An Er:fiber comb is delivered to two branches and amplified in an Yb:fiber and an Er:fiber amplifier, respectively. We demonstrate that the two-branch DFG can yield the spectrum tuned over an octave in a fan-out periodically poled lithium niobate. Thus, we obtain an optimized poling period profile and design the aperiodically poled ${\rm Mg}{:}{{\rm LiNbO}_3}$. The results demonstrate that broadband combs can be generated in the MIR atmospheric window.
