High Power Laser Mirrors for Femtosecond Applications
High damage threshold laser mirrors designed for applications with femtosecond lasers.
Produced using advanced IBS coating technology.
New ultra high damage threshold laser mirrors are designed for applications with femtosecond lasers.
These mirrors are produced using advanced IBS coating technology.
Mirrors design wavelengths include 515 nm, 800 nm, 1030 nm and broadband 720-880 nm range with reflection values R>99.8%.
Laser induced damage threshold was measured at mirror design wavelength with 50 fs pulse, 100 Hz under ISO standard 21254-2 1000-on-1 conditions.
