Free-Running Ring Quantum Cascade Laser with 50 kHz Linewidth
Alexandre Parriaux, Ina Heckelmann, Mathieu Bertrand +3
We report on the noise characterization of a free-running ring quantum cascade laser resonator emitting a single frequency mode around 7.7 m. Using a gas cell filled with NO…

Coherence analysis of tightly locked mid-infrared quantum cascade laser frequency combs
Alexandre Parriaux, Kenichi N. Komagata, Mathieu Bertrand +3
Frequency combs are powerful tools for many applications and high performances are achieved by stabilizing these lasers. For operation in the mid-infrared, quantum cascade lasers (…

Coherent Control of Mid-Infrared Frequency Comb by Optical Injection of Near-Infrared Light
Kenichi N. Komagata, Alexandre Parriaux, Mathieu Bertrand +5
We demonstrate the use of a low power near-infrared laser illuminating the front facet of a quantum cascade laser (QCL) as an optical actuator for the coherent control of a mid-inf…
