Abstract

We report on an integrated path Differential Absorption Lidar (IP-DiAL) instrument based on a new 3.3 - 3.7 μm range transmitter for multi-species atmospheric gas detection and quantification. This new transmitter is an amplified nested cavity optical parametric oscillator pumped by a 2kHz, nanosecond, fiber crystal amplified, microlaser. This transmitter allows us to perform multi-wavelength and multi-species IP-DiAL measurements over an extended range up to 200 m in the 3.3 to 3.7μm range. Demonstration of its capability for atmospheric methane and water vapor simultaneous detection is presented.
