Abstract
We developed a laser long-path absorption lidar system using a pas correlat ion method for measuring atmospheric methane. This technique uses a broad-b and laser and a pas correlation cell. We developed a potassium titanyl arse nate (KTA) optical parametric oscillator at 3.416 mu m for the laser source . The optical round-trip path length is 20 m. The experiment was carried ou t using this system. It was estimated that the error in the density of meth ane is 4.4 ppm for measurement within 1 s.
