Title: Dual frequency combs at 3.4 µm with subhertz residual linewidths
Published: May 01, 2010
Abstract: Two coherent 1.5-µm frequency combs are transferred to 3.4 µm by difference frequency generation with a 1064 nm cw laser. From a multi-heterodyne measurement, the residual linewidth between the comb teeth is resolution-limited at 200 mHz.
