Low Loss Hologram Filters for the Infrared

We propose to develop a new type of wavelength selective mirror for mid and long wave infrared optics. Based on surface structure waveguide holograms, the new technology approach promises to deliver high performance combined with the ability to vary thefilter characteristics by simple modification of the hologram parameters. The novel filters are also expected to provide a significant cost advantage due to inexpensive fabrication techniques. Produce rugged, low loss, wavelength selective optics for midand long wave infrared devices. Commercial applications include pollution monitoring, laser material processing such as cutting and welding, environmental sensors, and medical lasers.
