Atmospheric Mercury in China Studied with Differential Absorption Lidar [PDF]

open access: yesEPJ Web of Conferences, 2020
Mercury is a very serious environmental pollutant which is intensely studied by many researchers. China is a main producer and consumer of mercury. We have pursued extensive monitoring of atomic mercury using the differential absorption lidar (DIAL ...

Energy calibration of integrated path differential absorption lidars [PDF]

open access: yesApplied Optics, 2018
The stringent requirements for energy reference measurement represent a challenging task for integrated path differential absorption lidars to measure greenhouse gas columns from satellite or aircraft. The coherence of the lidar transmitter gives rise to speckle effects that have to be considered for accurate monitoring of the energy ratio of outgoing ...

Stabilized master laser system for differential absorption lidar [PDF]

open access: yesApplied Optics, 2010
Wavelength accuracy and stability are key requirements for differential absorption lidar (DIAL). We present a control and timing design for the dual-stabilized cw master lasers in a pulsed master-oscillator power-amplifier configuration, which forms a robust low-cost water-vapor DIAL transmitter system.
