NO Monitoring by a Tunable solid-State UV DIAL

摘要

A differential absorption lidar (DIAL) system, based on a tunable solid-state Ti:sapphire laser, was developed for nitric oxide monitoring in the UV region. The UV light was generated through second-harmonic generation (SHG) of sum-frequency mixing (SFM) between a Ti:sapphire laser, pumped by the SH of a Nd:YAG laser, and the fundamental of a second Nd:YAG laser. As a demonstration of DIAL capability, the spatial distribution of NO emission from a diesel engine was investigated.
