TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This SBIR phase I project proposes a tunable single frequency high energy fiber laser system for coherent Lidar systems for remote sensing. Current state-of-art technologies can not provide all features of high energy and efficiency, compactness, narrow linewidth, super frequency and power stability, low noise, and high extinction ratio at the same time. PolarOnyx proposes, for the first time, a high energy (100 mJ) single frequency (< 1 KHz) PCF fiber laser transmitter to meet with the requirement of solicitation. This proposal is based on the spectral shaping sub-mJ fiber laser we have achieved in our labs. In the high power amplifier stage, PolarOnyx proposes an innovative fiber based regenerative amplifier approach by employing our patent pending proprietary technologies in fiber lasers, that will be able to operate at low repetition rate (10 Hz to 1 kHz) and reach high energy level of 100 mJ. These will make the fiber laser transmitter system superior in terms of wall plug efficiency (over 30%), energy(100 mJ), noise, size, and cost. A tabletop experiment will be demonstrated in Phase I time frame for proof of concept. A compact prototype will be delivered in Phase II.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Immediate NASA applications include LISA, coherent communications and lidars. By frequency doubling to 532 nm and quadrupling to 266 nm, it will be able to find other applications for optical sensing systems. Other military applications include coherent systems for airborne lidars and laser transmitter for satellite communications.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
• Medical equipment and biomedical instrumentation. The high power laser can be applied to ophthalmology, refractive surgery, photocoagulation, general surgery, therapeutic, imaging, and cosmetic applications. Biomedical instruments include those involved in cells or proteins, cytometry, and DNA sequencing; laser Raman spectroscopy, spectrofluorimetry, and ablation; and laser based microscopes.
• Military / aerospace. The proposed fiber laser can be directly used in military applications, and space, aircraft, and satellite applications such as LIDAR systems, remote sensing system, illuminator system, and phase array antenna system.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
