The present knowledge of the Mars atmosphere is greatly limited by a lack of global measurements of winds and aerosols. Hence, measurements of height-resolved wind and aerosol profiles are a priority for new Mars orbiting missions. We have designed a

Laser Beam Shaping XIX.
A high-energy, dual-pulse, injection seeded pump laser operating at 1064 nm is an enabling technology for several airborne and space-based trace gas lidar systems. In a NASA SBIR funded Phase I effort we performed proof of principle testing of an app
