Project Description

Laser Transmitter for Space-Based Atmospheric and Oceanographic LIDAR
echnical Abstract: IThis Phase II SBIR program will build on successful Phase I work to provide Technology Readiness Level 4 (TRL-4) laboratory brassboard demonstration of laser sources and non-linear wavelength converters with significant improvements in efficiency and reduction in size, weight, and power consumption compared to systems currently available for space-based instruments planned for the coming 10 to 15 years. This new-generation technology is needed to reduce the size and weight of flight hardware to make it compatible with affordable, more capable satellite payloads. In particular we propose to demonstrate a novel laser transmitter architecture capable of providing a factor of two to three higher average power, pulse energy, and efficiency than laser systems flown on first-generation space-based active remote sensing systems. Our proposed program also includes brassboard demonstration of a highly-efficient wavelength conversion to the blue spectral region (450-500 nm) desired for oceanographic lidar sensors, of interest both for ACE and nearer-term Earth Venture missions.
