Remote measurement of atmospheric mercury using differential absorption lidar [PDF]

Optics Letters, 1982
Atomic mercury in the atmosphere was detected by the differential-absorption lidar technique. Laser light at the mercury resonance wavelength of 253.65 nm was generated by anti-Stokes shifting in H(2) of the frequency-doubled output from a Nd:YAG-pumped dye laser.

Advances in Diode-Laser-Based Water Vapor Differential Absorption Lidar

EPJ Web of Conferences, 2016
An advanced diode-laser-based water vapor differential absorption lidar (WV-DIAL) has been developed. The next generation design was built on the success of previous diode-laser-based prototypes and enables accurate measurement of water vapor closer to ...
