Abstract
We report the generation of up to 0.7 mW of narrow-linewidth radiation at by difference frequency mixing of a Nd:YAG-seeded 1.6-W Yb fiber amplifier and a diode-laser-seeded 0.6-W Er/Yb fiber amplifier in periodically poled . A conversion efficiency of 0.09%/W was achieved. A room-air spectrum acquired with a compact 80-m multipass cell and a dual-beam spectroscopic configuration indicates an absorption sensitivity of , corresponding to a sub-parts-in- sensitivity (0.8 ppb).
