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…

Non-resonant Optical Injection Locking in Quantum Cascade Laser Frequency Combs
Alexandre Parriaux, Kenichi N. Komagata, Mathieu Bertrand +4
Optical injection locking of the repetition frequency of a quantum cascade laser frequency comb is demonstrated using an intensity modulated near-infrared light at 1.55 m illumi…

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 (…
