A narrowband infrared source based on orientation-patterned GaAs for standoff detection of chemicals

Résumé

This paper presents our work on a pulsed single-frequency tunable optical parametric oscillator based on orientation-patterned gallium arsenide. Owing to crystal temperature tuning, this source covers the 10.2–11.2 and 7.6–8.6 μm ranges in single-longitudinal mode operation with a linewidth below 30 MHz. Standoff detection of ammonia around 10.35 and 10.5 μm is performed by implementing this source in an Integrated Path Differential Absorption Lidar (IP-DIAL) setup.
