Yag Pumped Dye Laser for the HIPAS Arctic Lidar
Abstract
This is a 1997 Defense University Research Instrumentation Program (DURIP-97) award of a laser for the lidar at the UCLA HIPAS Observatory, Fairbanks, Alaska. The new 20 Hz laser will be used primarily to study the arctic sodium layer, between 90 to 130 km altitudes. It can also be tuned from 540 to 850 nm, which includes the resonant lines of barium (Ba, 553.5 nm), cesium (Ca, 852.1 nm), lithium (Li, 610.4 and 670.8 nm), potassium (K, 766.4 nm), and rubidium (Rb, 780.0 and 794.8 nm), as well as the important sodium (Na, 589.0 and 589.6 nm) lines. The new laser will emit nominally 150 mJ pulses at 590 nm, making it possible to monitor the sodium layer almost in real time with the HIPAS 2.7 meter diameter lidar collector.
