Edmund Optics® Launches New Ultrafast Enhanced Silver Coatings

Ideal for Ultrafast Systems

The new Ultrafast Enhanced Silver Coating is ideal for low-to-medium power ultrafast lasers and features an average reflectivity > 99% from 600-1000 nm at a 0° AOI, as well as R_s > 99% from 540-1000 nm and R_p > 98,5% from 730-870 nm at a 45° AOI.

The coating’s group delay dispersion (GDD) is 0 ± 20 fs² from 600-1050 nm at a 0° AOI. This is  particularly beneficial for minimizing the propagation time difference caused by chromatic aberration and the temporal spreading of ultrafast laser pulses.

The coating also features typical laser induced damage thresholds (LIDTs) of:

•  0,3 J/cm², 100 Hz, 48fs FWHM, 800 nm, S-Pol, 1 pulse
• 0,16 J/cm², 100 Hz, 48fs FWHM, 800 nm, S-Pol, 1000 pulses

Highly Customizable

The standard Ultrafast Enhanced Silver Coating from EO was designed for titanium-sapphire ultrafast lasers, but the design wavelength can be customized for different ultrafast lasers such as ytterbium-doped lasers. The ability to customize, along with the flexibility to use many different substrate materials, provides many options to tailor the coating for your exact requirements.
