TL;DR: In this article, a coherent Doppler lidar at 2 m wavelength has been built with higher output energy 100 mJ than previously available, based on diode-pumped Ho:Tm:LuLiF, a recently developed laser material that allows more efficient energy extraction.

TL;DR: A 2 microm wavelength, 90 mJ, 5 Hz pulsed Ho laser is described with wavelength control to precisely tune and lock the wavelength at a desired offset up to 2.9 GHz from the center of a CO(2) absorption line.

TL;DR: An all fiber linear frequency modulated continuous wave (FMCW) coherent laser radar system is under development with a goal to aide NASA s new Space Exploration initiative for manned and robotic missions to the Moon and Mars as discussed by the authors.

TL;DR: This paper provides a description of the DL system and presents results obtained from these flight tests, including performance in a series of helicopter flight tests over the California desert.

TL;DR: The NDL was mounted in an instrumentation pod aboard an Erickson Air-Crane helicopter and flown over various terrains and was one of several sensors tested in this field test by NASA's Autonomous Landing and Hazard Avoidance Technology (ALHAT) project.
