100W High Efficiency 1550 nm Pulsed Fiber Laser

High peak power short pulsed lasers have been considered to be an enabling technology to build high power transmitters for future deep space high rate space communications. However, to achieve a high power at 100W level with a short pulse width and >25% wall plug efficiency still remains an issue unsolved. PolarOnyx proposes a novel approach targeting to make high repetition rate high peak power 100W fiber laser at 1550 nm and resolve the issues of modulation induced chirp, pulse distortion and nonlinear effects by employing our proprietary technologies in specialty fibers, spectral shaping and pulse shaping techniques. Space qualification will also be addressed in laying out the pathway towards space deployment. A tabletop demonstration will be carried out at the end of Phase 1. A prototype will be delivered at the end of Phase II.

For future NASA's deep space missions, high efficiency and high power pulsed fiber lasers have been considered to be an enabling technology to build high power transmitters.The proposed short pulse high power fiber laser approach can also be used in other applications, such as space, aircraft, and satellite applications of LADAR systems and communications. PolarOnyx will develop a series of products to meet various requirements for NASA/military deployments.

High power fiber lasers represent the next generation of critical optical components needed to build the coherent optical communications of the future and cable TVs that will deliver increased communication bandwidth and improved Quality of Service end users. The market for the application is growing and will be of great potential of hundreds of millions market. Other commercial applications: -Material processing, includes (1) metal processing such as welding, cutting, annealing, and drilling; (2)semiconductor and microelectronics manufacturing such as lithography, inspection, control, defect analysis and repair, and via drilling; (3) marking of all materials including plastic, metals, and silicon; (4) other materials processing such as rapid prototyping, desk top manufacturing, micromachining, photofinishing, embossed holograms, and grating manufacturing. -Medical equipment in ophthalmology, refractive surgery, photocoagulation, general surgery, therapeutic, imaging, and cosmetic applications. Biomedical instruments that involved in cells or proteins, cytometry, and DNA sequencing; laser Raman spectroscopy, spectrofluorimetry, and ablation; and laser based microscopes.

This is early/mid-stage (TRL 6) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
