NASA launched the ICESat-2 research satellite into space in September 2018. The satellite carries a photon-counting laser altimeter called the Advanced Topographic Laser Altimeter System (ATLAS) that can measure the elevation of ice sheets, glaciers, sea ice, forests, and more in unprecedented detail. The laser beams are at 532 nanometers, and the laser fires 10,000 pulses per second, allowing ATLAS to take measurements every 2.3 feet along the satellite’s ground path. The laser system uses a unique growth technology of RTP Q-switch crystal developed by Raicol Crystals to produce precise pulse laser systems.
