Diamond optics are characterized by significantly greater heat conductivity and a higher refractive index while also having outstanding mechanical properties.

Diamonds are not only a girl's best friend, but synthetic diamonds are also attractive as a material for laser optics: thanks to their extremely high refractive index and excellent heat conduction, laser optics made with them are ten times lighter than conventional laser optics. Fiber lasers in the kW range could, thus, operate with greater flexibility. Together with two other Fraunhofer institutes, Fraunhofer IAF has optimized the production and processing of diamonds in recent years, and the first cutting system with diamond lenses is being tested.
