Laser beam homogenizer: Top-Hat beam profileSpatial energy distribution of homogenized squared beam profileMany applications in laser metrology and laser material processing require a homogeneous intensity distribution of the laser beam over its complete profile. A so-called flat top intensity distribution can be generated by applying micro lens arrays, diffractive optical elements or aspherical lenses. Different systems for homogenizing laser radiation of high power laser sources have therefor been developed at blz.


BLZ - blz - ps-laser (IR, VIS, UV) - glass - 3D feature

Ultrashort pulsed laser material structuring enables visible as well as virtually non-visible structuring inside transparent materials such as glass as well as surface structuring of a large variety of different materials. Inside and surface structuring can provide 3-dimensional structures. The materials suitable for structuring can exhibit a large thermal expansion coefficient or have a low melting point. The achievable structure structure size can be as small as few microns, depending on material even 1 µm or less.

Glass is a versatile material and as such used in optics, electronics or biomedicine. However, the actual applications most often require an assembly of several glass parts. Although established methods for glass joining exist they have limitations making them highly application-specific. In contrast to this a novel approach for fusion welding of glass using ultra short laser pulses, extensively investigated by the blz over many years, offers much better versatility.
