Arbor Photonics Wins Fiber Laser Funding
ANN ARBOR, Mich., Sept. 23, 2010 — Fiber laser solutions provider Arbor Photonics Inc. has received SBIR Phase IB funding from the National Science Foundation for its work on “High Power Pulsed Fiber Lasers for EUV Lithography.”
The supplemental award will support production of its 3CTM (chirally-coupled core) optical fiber to achieve 200 W average power nanosecond lasers in the 1030 to 1090 nm wavelength range with single-mode output. The optical fiber uses an internal structure to produce single spatial mode output from very large core fibers.
Current 3C fibers with 35 µm central core diameters have already produced >100 kW peak power short pulsed output at power levels on the order of 100 W with M2 <1.1. To meet the increased performance goals, current fiber designs will be scaled to at least 50 µm core diameter.
The Phase IB award is an extension of a Phase I design effort that focused on developing high power, single-emitter fiber laser modules with exceptional beam quality and narrow linewidth. The features are anticipated to permit spectral combining of closely spaced laser channels to produce a single beam of nanosecond pulses with an average power of several kilowatts.
The system is intended for use in next generation laser produced plasma extreme ultraviolet lithography.

- 1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
- fiber laser
- A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
- Pertaining to optics and the phenomena of light.
- optical fiber
- A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote total internal reflection (TIR). It may be used singly to transmit pulsed optical signals (communications fiber) or in bundles to transmit light or images.
- A gas made up of electrons and ions.
- spatial mode
- Also known as transverse mode. The configurations of energy storage, relative to the structure of a laser resonator, that define the relative intensity distribution of the laser beam.
- Pertaining to or as a function of wavelength. Spectral quantities are evaluated at a single wavelength.
