Automated alexandrite transmitter for airborne DIAL experimentsAn account is given of the performance characteristics and development status of an automated dual alexandrite laser transmitter that is to be carried aloft by NASA's ER-2 research aircraft for water vapor DIAL experiments; these efforts are part of NASA's Lidar Atmospheric Sensing Experiment (LASE). The LASE transmitter encompasses control unit, thermal unit, and two lamp driver unit subsystems. Major reductions in system size and weight relative to commercially available alexandrite lasers were necessary; a total weight of only 330 lbs has been achieved. Attention is given to subsystem flight test results.
