IR optics

The dispersive mirror technology has already become well-established in systems based on Ti:Sa lasers (~800 nm) and near-infrared Yb:YAG lasers (~1030 nm). Recently, the interest has been broadened to thulium- and holmium-based lasers systems operating around 2 μm, as well as to novel technology based on 2.4 μm chromium doped zinc sulfide (Cr:ZnS) or chromium doped zinc selenide (Cr:ZnSe) extending the laser output to 3.2 μm. In order to further develop this technology, dispersive mirrors in the infrared spectral range of 1.6-4 μm are required.
