Compact 2 micron High Power Femtosecond Fiber Laser

Low cost and compact high power and high repetition rate laser is a critical component for next generation high repetition rate accelerators for DOE HEP programs. However, current technologies are limited and breakthrough technologies are needed. PolarOnyx is to develop a 2 micron high power (kW) and high repetition rate (1-100 MHz) femtosecond fiber laser system (Polaris laser system). PolarOnyx has demonstrated 20 W operation at 2 micron. PolarOnyx is planning to scale the power level to over 100 W (200W is our target) and 100 fs. Commercial Applications and Other Benefits: In addition to the HEP accelerator applications, material processing is a major commercial application for this project. This includes (1) Photonic device fabrications, such as waveguide, coupler, WDM, modulator, and switching; (2) all types of metal processing such as welding, cutting, annealing, and drilling; (3) semiconductor and microelectronics manufacturing such as lithography, inspection, control, defect analysis and repair, and via drilling; (4) marking of all materials including plastic, metals, and silicon; (5) other materials processing such as rapid prototyping, desk top manufacturing, micromachining, photofinishing, embossed holograms, and grating manufacturing.
