Raman-shifted Eye-safe Aerosol Lidar Development

Not Accessible

Your library or personal account may give you access

Abstract

The design and first observations of an eye-safe backscatter lidar system are presented. Unlike previous lidar developments using Raman scattering in methane, the pump beam is not focused and the cell is injection seeded to improve conversion efficiency and beam quality. The system is capable of operating in a dual-wavelength mode (1.064 µm and 1.543 µm simultaneously) for comparison or a completely eye-safe mode. The system is capable of transmitting over 200 mJ/pulse at 10 Hz. Aerosol backscatter data from vertical pointing periods are shown.
