Abstract
We are completing the construction and testing of a remote air pollution detection system that utilizes a 1.4–4-μm tunable LiNbO3 parametric oscillator source. The Nd.YAG pumped parametric oscillator operates under computer control at greater than 20% energy conversion efficiency. Bandwidths using grating, etalon line narrowing elements are less than 0.1 cm−1.
