"Green Photonics" at the LASER Fair in Munich

03.05.2011 - (idw) Laser Zentrum Hannover e.V.

In many areas of modern industrial manufacturing, it is possible to use the laser for protecting resources and for improved energy efficiency. The Laser Zentrum Hannover e.V. (LZH) will present examples of green photonics at the LASER fair in Munich, from May 23rd to 25th, 2011. The spectrum of themes dealing with the environmentally friendly use of light includes using laser technology for light-weight construction, for regenerative energy production, as an alternative to enviromentally harmful processes, or for new, energy-efficient laser systems.
For example, LZH laser technology can be used for processing CFRP materials (carbon fiber reinforced plastics). This technology is instrumental in innovative light-weight concepts for the aeoronautical and autobile industry. Expensive and costly raw materials can be reduced, and the use of fuel can be significantly lowered.
Also, the welding speed of gas-metal welding can be doupled using laser technology. This means that laser research at the LZH is a contributing factor to energy efficiency in production.
Lasers can also be used to reduce pollution, for example, for structuring the surface of glass. Laser technology can be used instead of chemical engraving or sandblasting, and cover-up foils and environmentally hazardous chemicals are no longer necessary.
LZH laser technology is also important in the production of regenerative energy. In this field, the laser can be used for welding glass tubes for higher quality solar receivers, or for increasing the energy efficiency of photovoltaic cells, or for lowering production costs for warm water solar collectors.
Furthermore, the LZH will present new fiber components which can be used in energy efficient fiber laser systems for material processing, or for medical technology, including a newly-developed, ultra-short laser oscillator based fully on fiber lasers. This oscillator can be exmployed for treating presbyopia. Visitors can also view lasers for use in outer space, or for highly precise measurements necessary for gravitational wave detection.
The development, modelling and online monitoring of laser optic coating processes will also be presented in Munich. In direct cooperation with customers, the LZH produces highest quality coatings and optical designs.
