Abstract
A novel laser-based absorption diagnostic technique based on off-axis paths in high-finesse optical cavities provides high measurement sensitivities (~2×10−10 cm−1). Applications to environmental monitoring and industrial process control using near-IR semiconductor diode lasers and mid-IR quantum cascade lasers will be presented.
