Sapphire wedge window can be used as isolating components. In addition to features similar to normal wedge windows, the sapphire wedge window has a harder, stronger, and more wear-resistant properties
Ricun offers wedged sapphire windows that eliminate fringe patterns and can be used to help avoid cavity feedback. Wedge Windows are useful for protecting a laser output from environmental effects and for beam sampling applications.
