offering fi bre lasers in addition to disk, diode, rod and CO2 lasers. Customers can use these lasers for applications in the multi-kilowatt range, in precision processing, in microprocessing or for laser marking. Trumpf positions itself as a one-stop shop for beam guidance, processing optic, and control and automation elements; all components are fully compatible with one another. To give users the best support in selecting an appropriate laser beam source, Trumpf has consolidated at its application centres around the world its experience and expertise gained from developing beam sources along with decades of experience in applications and laser integration. Here, customers will get the help they need to identify the right laser beam sources and to align production systems with one another optimally. The Trumpf product lines that will be exhibited at the show
Z-laser optoelektronik will be showing a blue 457nm emitting laser module based on solid state disc laser technology. This was created together with partners Xiton Photonics and the Institute for Medical Laser Technologies of ULM University. The objectives were ambitious with a beam quality of M²=1.0 and an optical power ›500mW and a compact overall size of 300 x 200 x 200mm. To achieve this kind of power and beam quality in such a small package a novel kind of pumping concept needed to be developed. By utilising an 880nm emitting laser bar, highly
include the TruFlow high power CO2
cooled CO2
lasers, TruCoax diffusion- lasers, TruDisk disk
lasers at up to 16kW, TruDiode direct diode lasers, TruFiber at outputs of 200-400W, TruPulse pulsed solid-state lasers, TruMicro short and ultra-short solid-state lasers, and TruMark beam sources in all relevant wavelengths for marking applications.

wItec will highlight the new True Surface Microsocopy mode. WITec’s new True Surface Microscopy mode allows confocal Raman imaging guided
effi cient pumping of the solid state disc was achieved in such a compact housing size. Bulky thermal masses were eliminated with this approach without affecting the performance of the laser. The air circulation based cooling mechanism manages without water or other costly and cumbersome equipment. This means that this is not uniquely a laboratory laser, but instead is designed and targeted to industrial and medical fi elds. A free space emitting version
of the novel blue disc laser will be presented. This laser version includes the optical system, the
air cooling ventilation as well as the electronics and user interface. For OEM clients it is possible to fully customise the system or simply offer the optical head including the disc and pumping resonator for integration into a customised system.

by surface topography. True Surface Microscopy follows the surface topography with high precision, so that even rough or inclined samples always stay in focus while performing confocal Raman imaging. To achieve this unique capability, the WITec alpha500 series integrates a highly precise sensor for optical profi lometry. The topographic coordinates from
the profi lometer measurement are used to perfectly follow the sample surface in confocal Raman imaging mode. The result is an image revealing optical or chemical properties at the surface of the sample, even if this surface is very rough or heavily inclined. On such surfaces this information was only partially accessible thus far and with the new imaging mode, samples that had previously required extensive preparation in order to obtain a certain surface fl atness can now be effortlessly and automatically characterised as they are.
