Tunable quantum cascade lasers for midinfrared spectroscopic sensing
Many gases of interest exhibit strong absorptions within the Mid-infrared (Mid-IR) region, spanning from 2.5 to 25 µm. To enable high-sensitivity spectroscopy, a robust coherent source in this range is required. Quantum cascade lasers (QCLs) possess inherent intersubband transitions that allow for t...
