    INNOSLAB lasers represent a new laser class which is suitable for a large variety of applications in different sectors of industry and research. With his features INNOSLAB lasers enable a variety of challenging applications with added value such micro-processing of glass, scribing, edge deletion, high throughput thin film structuring, and pumping of dye lasers.

    The technological impact of the innovation includes
    • improving existing manufacturing processes
    • enabling new production processes and new types of products
    • precision processing with small heat affected zones and high
    • high productivity in micro-processing
    • new design of drilled holes by changing the cross-sections along the
    hole depth
    • green processing with high energy efficiency
    • efficient pumping sources for dye lasers, OPO and OPA sources at high
    repetition rates

    The major sectors of industry which are profiting from the INNOSLAB lasers are:
    • Photovoltaic, e.g. scribing, drilling and cutting of Si-wafer, ablation
    of conduction or dielectric layers of thin film solar and crystalline
    Si solar cells
    • Display, e.g. structuring of conduction layer, sequential lateral
    crystallization of Si
    • Glass industry, e.g. micro drilling and high throughput subsurface
    • Scientific, e.g. pumping of dye laser, pumping of OPO and Ti:Saphire
    laser, particle imaging velocimetry
    • Electronics industry, e.g. drilling and cutting of printed circuit
    • Tool making and mechanical engineering, e.g. 3D rapid prototyping via

    All 3 applications have led to an outstanding innovation in the field of laser technology and are presented in detail including texts and photos on

    The Innovation Award Laser Technology is a European research prize awarded at 2-yearly intervals by the associations Arbeitskreis Lasertechnik e.V. and the European Laser Institute ELI. The award can be conferred on an individual researcher or on an entire project group, whose exceptional skills and dedicated work have led to an outstanding innovation in the field of laser technology. The scientific and technological projects in question must center on the use of laser light in materials processing and the methods of producing such light, and must furthermore be of demonstrable commercial value to industry.

    The international jury is consisting of 10 members that are recruited from industry and the research community. The jury’s decision was based principally on the following criteria:
    • Proven commercial benefit
    • Innovative quality of the resulting laser beam source, laser manufacturing
    or laser system
    • Scientific / technological quality of the underlying research
    • Creative approach to technology demonstrated by the designated individual or
    project group
    • Importance of the contribution of the applicant’s work to the overall
    innovative process

    Arbeitskreis Lasertechnik AKL e.V.
    Arbeitskreis Lasertechnik AKL e.V. is a registered non-profit association formed in 1990 by a group of companies and private individuals aiming to pool their experience and conduct joint public-relations activities in order to spread the use of laser technology in industry and promote the sharing of scientific ideas. The »Innovation Award Laser Technology« aims to reward excellent achievements in applied research and outstanding innovation in the field of laser technology and to shine a spotlight on their authors. In 2009, around 90 laser experts and enthusiasts were signed up as active members of the AKL network. The association’s activities include disseminating information on innovations in laser technology, organizing conferences and seminars, compiling educational material dealing with laser technology, stimulating the interest of future young scientists, and providing advice to industry and research scientists on questions relating to laser technology.

    European Laser Institute ELI e.V.
    Optical technology is taking an increasing hold on all domains of industry and science. Europe already possesses a strong position in this field by virtue of its numerous experts and excellent research and development facilities. Nevertheless, it has been realized that there is an urgent need to link the existing sources of know-how and expertise, and to enhance the performance of joint research activities. Consequently, the European Laser Institute (ELI) has created an efficient platform bringing together the necessary competence and knowledge on optical technologies. By promoting technology transfer within Europe, ELI aims to enhance the international lead of European industry and research in the field of laser technology and photonics. By working in close collaboration with existing national and international organizations, the ELI network of industrial and academic research institutions helps to influence R&D policy on a national and European level.
