Abstract
A compact transmissive phase retarder for large and high power laser beam applications is proposed. The laser beam is orthogonally incident on the flat input surface of the optical element and is emergent from the optical component via a second flat output surface. The cross-section of the optical element is characterized by a triangularly or trapezoidally folded surface. The folded surface replaces the inclined surface of bulk equivalent elements. The functionality of the device is provided by a multi-layer interferometric structure deposited on the folded structure.
