Absolute spectroscopy near 7.8 μm with a comb-locked extended-cavity quantum-cascade-laser
Abstract We report for the first time the frequency locking of an extended-cavity quantum-cascade-laser (EC-QCL) to a near-infrared frequency comb. The locked laser source is exploited to carry out molecular spectroscopy around 7.8 μm with a line-centre frequency combined uncertainty of ~63 kHz. The...
