Laser dispersing prisms can be used inside the cavity of a laser operating on very gain laser transitions, where even slight reflection losses may be intolerable. EKSMA Optics offers laser dispersing prisms made of BK7, UV FS, SF11 optical materials. Our standard prisms come in three different side lengths (15 mm, 25 mm or 50 mm). Prisms are made for maximum input beam diameter of 6, 12 or 22 mm. Custom fabrication and other types of prisms are available under customer request.
