Agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser

Agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser

Cavity ringdown spectroscopy (CRDS), relying on measuring the decay time of photons inside a high-finesse optical cavity, offers an important analytical tool for chemistry, physics, environmental science, and biology. Through the reflection of a slight amount of phase-coherent light back to the lase...
