Dilas has announced homogenized areal illumination high-power diode lasers. The homogenization of radiation has applications in hair removal and dermatology. The company is using active mixing of laser radiation with crossed microlens arrays, resulting in a defined rearrangement of the light. The process leads to uniformity of >95% with steep edges and no spikes in a square-shaped 12 x 12 mm spot with a working distance of 62 mm. The square shape is best for rasterization of larger areas with no overlap and very high coverage of the area. Other geometries are available. Homogenization optics are suitable for a variety of fast-axis collimated diode laser beams and can be attached to various of the company’s products, including the 12-bar water-cooled stack.
