Laser is a tool renowned for its speed and precision. Laser
manufacturing processes enable the joining of lightweight
structural components in the automotive industry and open
new vistas in the production of innovative energy storage
devices. They improve the efficiency of solar cells and increase
throughput in the production environment – and laser pro-
cesses also lead the way when it comes to innovative repair
and maintenance methods in the engine and turbine industry.
While encouraging this shift towards sustainability, laser sys-
tems at the same time make highly efficient use of energy.
Laser radiation is applied precisely where it is needed – with-
out unintended side-effects: Just one reason why our work in
R&D places major emphasis on green photonics.
Seven Fraunhofer Institutes will be showcasing an impressive
range of tailored light applications at LASER World of PHO-
TONICS 2011. Our primary focus is on contract research and
development work across the full spectrum of optical technolo-
gies, including optical design, laser source development, opti-
cal test and measuring systems, precision optomechanical sys-
tems, and laser micro and macro machining of a wide variety
of materials. We also offer tailor-made process and system
solutions, feasibility studies and expert consulting services.
Whatever your needs, we are very much looking forward to
having an opportunity to discuss them with you in person!

MICRO-OPTICS ANDNANO-OPTICS
Micro- and nanostructured optics are key components of
modern optical systems. Electron beam lithography technolo-
gies specially enhanced for optics have made it possible to
manufacture micro-optical components at the highest resolu-
tion on substrates measuring up to 12 inches in diameter. Laser
lithography processes can be used to structure curved surfaces.
By combining both methods, microstructures with different
levels of feature size can be implemented on an optical ele-
ment. Fraunhofer researchers develop processes for the
replication and manufacture of molding tools that can be used
to produce low-cost precision optics for the consumer market.

reduce both costs and CO2 emissions. Fraunhofer develops
optics tailored to each specific application. Lightweight metal
mirrors manufactured in ultra-precision processes are fitted in
