OPOs pumped external to the laser cavity suffer from inefficiencies due to phase distortions and optical losses caused by various intervening optical components and the single pass nature of the pump laser. The internal cavity OPO has the advantage o

We report the progress in the development of a compact mid-infrared differential absorption lidar (DIAL) for ground-based and airborne monitoring of leaks in natural gas pipeline systems. This sensor, named Lidar II, weighs approximately 30 kg (70 lb

One of the limits to the sensitivity of differential absorption lidar (DIAL) when using a topographic reflector is the spectralvariation of the reflectance of the topography (differential albedo). This is especially a problem when DIAL is attemptedfr

A compact (2'6' X 2'5' X 1'1') 3.30 - 3.47-micrometers DIAL lidar has been constructed for base remediation and chemical monitoring. The lidar system is designed for short range (0.5 km maximum) aerosol backscatter detection of light hydrocarbons wit

Differential absorption lidars (DIAL) in the mid-infrared (2 - 5 micrometers ) are used to monitor various chemical species. Two wavelengths are required to perform the differential absorption measurement: an `on' line and an `off' line. Previously,
