Superpolished Mirrors
BOULDER, Colo., June 6, 2011 — New superpolished laser mirrors from REO offer low loss, making them suitable for use in demanding applications.
Microroughness is <0.5 Å, allowing them to achieve scattering loss of <5 ppm and finesse of 200,000 when incorporated into optical cavities. Ion beam-sputtered coatings are used to take advantage of the ultrasmooth surfaces and deliver reflectivities of >99.998% at any wavelength in the 450-nm to 2-µm range.
The mirrors can be produced on a number of...
