Ultra-fast, high-power lasers, generating pulses of sub-picosecond durations (<10-12 seconds), are becoming increasingly important in application areas ranging from micro-machining to non-intrusive surgery, bio-detection and Homeland Security. Until now, the required high-power ultra-fast radiation could only be provided by bulk, solid-state lasers, which have the undesirable features of high cost, large size and poor reliability. New laser sources, with improved reliability, reduced cost and reduced size will further expand the market potential for high-energy pulsed optical systems. Short-pulse fibre lasers are compact, and cost-effective, offering size and cost-reductions of up to 10 times compared to equivalent bulk-laser systems.
Ampere University of Technology (TTY) - the coordinating organization - has already demonstrated ultra-short pulse fibre lasers operating at 1.5-¿m and unique picosecond system operating in the 980-1100 nm wavelength range. These systems represent a consistent starting point for the experiments in URANUS. The complimentary expertise of URANUS partners (Fianium-NewOptics in ultra-fast high-power fibre lasers, Stratophase in nonlinear frequency converters, NKT in photonic crystal fibres, INESC PORTO in fibre Bragg grating technology and CoreLase in high-power fibre systems) ensures a high likelihood of achieving technological break-throughs by expanding the power, operating wavelength, and pulse-width limits of cost-effective ultrafast fibre systems.
The proposed fibre systems combine a unique blend of state of the art semiconductor and micro-optics technology, advanced amplifier and photonic crystal fibres, fibre components and non-linear materials and applications. These systems will thus be capable of providing higher average powers and comparable pulse energies and peak powers to existing solid-state laser systems but at a fraction of the cost and in a compact, robust form.
