Abstract

We present a low-noise and high power per comb line dual-comb source based on a PPLN OPO and an Yb:YAG pump. Both the laser and OPO are spatially-multiplexed single-cavity dual-comb sources. The system operates at a repetition rate of 250 MHz, and the relatively long pump pulse duration of around 900 fs leads to a high power per comb line of >60 μW in the idler at 3500 nm. The idler is tunable from 2900 nm to 4170 nm. The system runs at over 15 kHz repetition rate difference, enabling comb-line-resolved dual-comb spectroscopy measurements in free-running operation.
