Free-electron laser applications in environmental and atmospheric research

The PEARL (Pan-oceanic Environmental and Atmospheric Research Laboratory) initiative has been proposed by a consortium of academic, industrial, and national laboratory organizations, led by the School of Ocean and Earth Science and Technology and the Free-Electron Laser Group of the University of Hawai`i, with the objective of installing a kilowatt-class broadly-tunable scanning lidar (built around a pulsed RF linac free-electron laser transmitter) aboard an ocean-going platform for use in the real-time detection and mapping of a broad range of transient atmospheric constituents and dynamic phenomena.

The Laser Remote Sensing Group advises the PEARL project on system performance aspects and in development of the associated research program.
