Stay up to date on the latest news and research related to Earth Science, from the use of lasers and optics to understand our planet to the impacts of climate change.
A team of researchers has recently announced the successful development of a high-efficiency, nanosecond pulsed blue laser operating at 486.1 nm for Advanced Bathymetric Lidar. They achieved this feat by utilizing a frequency quadrupled thulium-doped fiber amplifier (TDFA), marking the first time such a device has been implemented for this purpose.
Airborne lidar bathymetry, a cutting-edge technology that combines light detection and ranging (lidar) with bathymetric principles, has become an invaluable tool for mapping underwater topography.
Researchers at the University of Science and Technology of China have developed a near-infrared (NIR) dual-channel oxygen-corrected laser heterodyne radiometer (LHR) to measure the vertical profile of wind fields in these regions with high accuracy.
