TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This SBIR will develop core Yb laser technology that is higher than 50% optical to optical efficient with pulse energies up to 300uJ/pulse in the all fiber version and up to 5mJ using planer waveguide power amplifiers. This SBIR try to newest fiber technology – 3C fiber as the gain medium fiber to improve the stability of beam profile, pointing and polarization stability to suitable for space working environment. The proposed laser transmitter is based on Fibertek's proprietary laser architecture that utilize state-of-the-art optical and ultra high bandwidth RF analog and digital electronic component technologies.

Technical Objectives of SBIR program:
Analysis and Design of high energy, high efficient fiber based 3C amplifier transmitter at the 1030 nm.
Laboratory Benchtop Demonstration of 300uJ/pulse operation at 10 kHz with 1.5 ns pulse width and >17dB PER
Design fibre-PWG hybrid amplifier and have PWG fabricated and tested
Work Plan for Phase I:
Model & optimize both type amplifiers' parameters for high energy, high efficiency and stability
Build fiber based lidar transmitter and demonstrate proposed operation in the laboratory environment.
Initial investigate on the PWG optical characterizations and amplification performance.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed all fiber version amplifier system meets all LIST mission transmitter's specifications
The all fiber version amplifier system can used as the OPO/OPA pumping laser for ASCENDS mission Lidar transmitter.
The all fiber version amplifier system can used the seed laser for ICEsat high energy hybrid amilifier transmitter.
The fiber-PWG amplifier system can directly used as ICEsat high energy hybrid amilifier transmitter.
