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.

VITO - Laser transformation hardening - 150W diode laser

Laser transformation hardening is a technology using a laser beam scanning the surface of a component. the substrate component is typicalle a steel alloy or cast iron with a carbon content between 0.2-1.5%. The irradiated compound is experiencing a quick heating and cooling cycle during which martensite formation occurs. This martensitic phase introduces a higher hardness of the surface of the steel component.
