Solutions for your Market

08.05.2013
From May 13th to 16th, 2013, the Laser Zentrum Hannover e.V. (LZH) will be showing highlights from their development labs at the world’s largest fair for lasers, the Laser World of Photonics in Munich.
Under the motto „Solutions for your Market“, the LZH will be showing their competence from the areas of precise laser components, innovative laser systems, laser precision processing and interesting applications for laser-based manufacturing technology.

Precise Laser Components…
are the basis for successfully optimized laser processes. The LZH is competent in both programming optical monitoring systems and highly precise equipment control, and in mastering innovative coating processes.
Various processes for optics characterization, among others to determine optical losses or laser-induced damage thresholds, belong to our service portfolio. Do you need special coatings? The LZH offers layer systems for optical and sensory applications with layer thicknesses from several nanometers to 100 µm, including small job lots. Our experts also help you image dielectrical systems based on discrete diffraction indices or gradient systems (Rugate filters).

Innovative Laser Systems…
are one of the main business branches of the laser experts in Hannover. The researchers consider it to be a special challenge to find solutions for extremely sensitive applications, for example for gravitational wave detection. Together with the Albert Einstein Institute Hannover (AEI), they have developed a prototype of a single-frequency, highly integrated 1 µm fiber amplifier system which shows high stability. Due to brilliant beam quality, the system can be used for measuring or generating quantum optics phenomena, for laser-based metrology, or for non-linear frequency conversion (SHG, OPO).

Stability under suboptimal external influences is also important for micro-machining plastics, or for spectroscopy applications. High wavelength and output stability are characteristics of the current seed laser for backend fiber amplifiers. An ultrashort pulsed thulium oscillator, which is based completely on polarisation maintaining fibers, emits at 1.98 µm, and does not need to be readjusted.

A special highlight for material analysis is the LIBS laser head, made for use under extremely rough testing conditions. Convince yourself of the specifications of this extremely lightweight system for laser-induced plasma spectroscopy, with a wavelength of 1053 nm, pulse energy > 1 mJ, pulse repetition rate
Precision Laser Processing…
means being able to adapt the tool “laser” to individual, complex production and manufacturing processes. For example, lasers can be used to structure strain gauges directly onto the surface of workpieces with complex forms, such as bearing or motors. The thin-film sensors can be used to reduce downtime by monitoring tooling, or by detecting strain, exactly and in realtime. Conventional foil sensors, which are glued onto a workpiece, have a limited lifetime in rough environments, which laser-based sensors can easily overcome.
Further examples of innovative developments from the LZH which will be shown in Munich are water repellent surfaces, highly efficient solar cells or cutting of thin glass elements.

Laser-based Manufacturing Technologies…
play a key role in production. From manufacturing tiny metal workpieces using a laser melting process up to welding 23mm thick steel sheets for shipbuilding and pipelines – in Hannover we do research and development in all dimensions.
Processing of modern fiber reinforced plastics for lightweight construction is a challenging project for the LZH. CFRP (carbon fiber reinforced plastic) is made of different materials in inhomogeneous layers, which means that spectral absorption and melting and vaporization temperatures are different for each material in the composite. Laser applications are being pushed and promoted, so that lightweight yet precise mass production of CFRP is possible. Ask the experts at the LZH about the latest developments in this area!
