Laser Mirrors for ultra short pulses in the femto-second range successfully qualified

Optics Balzers has developed and successfully tested a special dielectric layer system. The PARMS coating technology made it possible to manufacture 45°-HR mirrors for 1030nm for which a destruction threshold of 0.44J/cm² at 210fs was established. Typically, these are used in ultra-short pulsed systems of Yb:YAG solid-state lasers. These mirrors, deposited on 1“ substrates, are available for demonstration.

In the next step, the process will be optimised to improve the results obtained so far. Besides, designs for other typical ultra-short pulse wavelengths will be tested, among them mirrors for titanium-sapphire lasers at 800nm and erbium lasers at 1550nm.
