Glass that has minimum reflection and absorption at 1550nm

jeic

I am building an enclosure for my laser that emits at 1550nm. I need to integrate a window for the laser light to pass through. Anybody have any recommendations on what kind of glass would work best so that the optical losses are kept at a minimum? Ideally, it would be commercially available and not be too expensive. Thanks.

jeic, You may look into using chalcogenide glass. It is known to pass radiation at 1550 nm with little transmission loss. You also might contact a specialty optical glass manufacturer. They typically provide technical assistance free of charge:
