Fiber lasers and amplifiers for space-based science and exploration
2012
We present current and near-term uses of high-power fiber lasers and amplifiers for NASA science and spacecraft
applications. Fiber lasers and amplifiers offer numerous advantages for the deployment of instruments on exploration
and science remote sensing satellites. Ground-based and airborne systems provide an evolutionary path to space and a
means for calibration and verification of space-borne systems. NASA fiber-laser-based instruments include laser
sounders and lidars for measuring atmospheric carbon dioxide, oxygen, water vapor and methane and a pulsed or
pseudo-noise (PN) code laser ranging system in the near infrared (NIR) wavelength band. The associated fiber
transmitters include high-power erbium, ytterbium, and neodymium systems and a fiber laser pumped optical parametric
oscillator. We discuss recent experimental progress on these systems and instrument prototypes for ongoing
development efforts.
