Technical Abstract (Limit 2000 characters, approximately 200 words)

Fibertek proposes to develop a high efficiency, ultra-compact master oscillator/power amplifier (UCMOPA) for use in the next generation of space-based cloud and aerosol lidar systems. The Phase I goal is a laser optics module design that is < 1/7 the volume and weight and is 75% more efficient than the original CALIPSO laser transmitter. This increased efficiency reduces the power required for the same outputs as CALIPSO by 40%. For both systems there is a separate electronics module. We anticipate a similar reduction in the size of the electronics module in Phase II, but that will not be part of the Phase I studies. The proposed system would support a backscatter lidar system, one the four primary instrument types identified as relevant to the S1.01 Lidar and Remote Sensing topic in the 2019 Phase I SBIR call. A summary of key features that will be incorporated into the proposed laser module are given below.

  1. An ultra-compact master oscillator/preamplifier design that can generate > 100 mJ/pulse, near single-frequency output.
  2. Use of a passive Q-switch in the compact ring oscillator to achieve near single-frequency operation.
  3. A compact, high efficiency gain head for use in the final power amplifier that incorporates an off-axis design to improve the fill factor and efficiency. The power amplifier will be capable of generating > 250 mJ/pulse with 100 mJ/pulse input.
  4. Full conductive cooling and opto-mechanical packaging that is compatible with a space-based mission.


Potential NASA Applications (Limit 1500 characters, approximately 150 words)

The high-efficiency, ultra-compact MOPA we are proposing to design and build will reduce the size and weight of a space-qualifiable laser that can be used in multiple space-based and airborne lidar systems including the following:

  1. The next-generation of airborne and space-based cloud, aerosol, and ocean lidar systems.
  2. A variety of airborne and space-based lidar systems that measure properties of the Earth’s surface. These include global ice characterization, 3D structure of the terrestrial ecosystem, and high-resolution global topography.


Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

There is significant commercial interest in the high-efficiency, compact laser being proposed.

1.   As the transmitter for the next generation Ball Aerospace Optical Autocovariance Wind Lidar system.

2.   As the transmitter for small satellite measurements of surface and atmospheric conditions for the DoD in a  Navy National Oceanographic Partnership Program we are supporting.
