Driven by the end-users requirements and needs, the main objective of the HIPERDIAS project is to demonstrate high throughput laser-based manufacturing using high-power, high-repetition rate sub-1ps laser. Although the laser system to be developed within HIPERDIAS can address other material processing applications, the focus here will be 3D structuring of silicon at high-speed, precision processing of diamond material and fine cutting of metal for the watch and the medical industry. Chirped Pulse Amplification (CPA) approach based on highly efficient compressors gratings will be implemented in order to minimize the overall losses of the laser system. The final targets of the project are to demonstrate: - a 10-times increase of ablation rate and productivity of large area 3D-structuring of silicon - a 10 times increase of speed in fine cutting metals - an increase of process speed (6-10 times) at a low processing tools cost of diamond machining Therefore, the laser parameters, as well as the beam shaping, beam guiding (based on Kagom fibers) and machine systems will be developed and optimized to fulfill the above manufacturing targets. The laser architecture will be based on fully passive amplifier stages combining hybrid (fiber-bulk) amplifier and thin-disk multipass amplifiers to achieve sub-500fs at an average output power of 500W and sub-1ps at an average output of 1kW, at a repetition rate of 1-2 MHz. Furthermore, second harmonic generation (SHG, 515 nm) and third harmonic generation (THG, 343 nm) will be implemented to allow processing investigation at these wavelengths. At 515 nm (respectively 343 nm) an average power of >=250W (respectively >=100W) shall be demonstrated.

FEMTOPRINT is to develop a printer for microsystems with nano-scale features fabricated out of glass. Our ultimate goal is to provide a large pool of users from industry, research and universities with the capability of producing their own micro-systems, in a rapid-manner without the need for expensive infrastructures and specific expertise. Recent researches have shown that one can form three-dimensional patterns in glass material using low-power femtosecond laser beam. This simple process opens interesting new opportunities for a broad variety of microsystems with feature sizes down to the nano-scale. These patterns can be used to form integrated optics components or be developed by chemically etching to form three-dimensional structures like fluidic channels and micro-mechanical components. Worth noticing, sub-micron resolution can be achieved and sub-pattern smaller than the laser wavelength can be formed. Thanks to the low-energy required to pattern the glass, femtosecond laser consisting simply of an oscillator are sufficient to produce such micro- and nano- systems. These systems are nowadays table-top and cost a fraction of conventional clean-room equipments. It is highly foreseeable that within 3 to 5 years such laser systems will fit in a shoe-box. The proposal specific objectives are: 1/ Develop a femtosecond laser suitable for glass micro-/nano- manufacturing that fits in a shoe-box 2/ Integrate the laser in a machine similar to a printer that can position and manipulate glass sheets of various thicknesses 3/ Demonstrate the use of the printer to fabricate a variety of micro-/nano-systems with optical, mechanical and fluid-handling capabilities. A clear and measurable outcome of Femtoprint will be to be in a situation to commercialize the femtoprinter through the setting-up of a consortium spin-off. The potential economical impact is large and is expected in various industrial sectors.

FLAME will leverage a current revolution in ultrafast laser science and lead to the commercial availability of amplified laser systems with significantly higher pulse repetition rates, higher average powers and shorter pulse durations than has been possible up to now. In addition, the project will develop sophisticated ion and electron imaging detectors tailored to the experimental research carried out with the novel laser systems. Work to be performed by the RTD teams will be carried out in three directions: Development of a high power and high speed extremely short pulse (<10fs) laser source and a tunable visible high power and high speed ultrafast laser source. Development of dedicated detection instrumentation that maximizes the benefits that can be obtained from working with these laser sources The technology that will be developed in the project offers One-two orders of magnitude higher repetition rates, one order of magnitude shorter pulse durations and higher average powers than commercially available laser amplifiers, existing fiber lasers or few-cycle oscillators A multi-dimensional detection apparatus tailored to ultrafast laser pulse characterisation with an improvement in signal quality by an order of magnitude The FLAME consortium consists of 4 SME participants and two leading research centers as RTD participants. The SME participants are today already present in the ultrafast market, or as providers of characterization/detection equipment. They are in an excellent position to offer new products shortly after the completion of the project. The path for exploitation of foreground in the FLAME project will follow the model generally leading to wide industrial acceptance of new laser technologies: Develop a solid technology base from the research carried out in the project Leverage this technology base for a rapid access to fast growing scientific markets Build on the relationship with scientific customers to develop new industrial markets Short term scientific applications include attosecond research and time-resolved spectroscopy, while mid-term industrial applications include materials science and semiconductor metrology.
