Coatings on large optics for laser fusion and petawatt systems

LASEROPTIK offers coatings made by IBS (ion beam sputtering) on large substrates up to diameter 550 mm or equivalent rectangular shapes. Coating designs can be optimized for high LIDT and complex GDD specifications, e.g. for Petawatt laser applications.

Ultimate LIDT coatings for CW laser optics

With a CW LIDT of more than 86 MW/cm² (irradiance), and >634 kW/cm (linear power density), LASEROPTIK pushed their IBS sputtered laser mirrors at 1070 nm to the max, using a R(30s)-on-1 test procedure. The samples reached the maximum available irradiance limit without being damaged. Tested by LIDARIS in 10/2025. Optics up to diam. 550mm can be coated using our ion beam sputtering technology, providing lowest losses and high thermal conductivity.
