An optical fiber heat exchanger includes an outer body and an inner body inserted into the outer body. The inner body includes a plurality of guide walls to guide a cooling liquid through the optical fiber heat exchanger to exchange heat from an optical fiber inserted in the optical fiber heat exchanger, a first set of parallel straight channels, extending along an inlet portion of the inner body, formed by a first subset of the plurality of guide walls, a set of U-shaped channels, extending through a transition section of the inner body, formed by a second subset of the plurality of guide walls, and a second set of parallel straight channels, extending along an outlet portion of the inner body, formed by a third subset of the plurality of guide walls.

An optical device may comprise an optical element holder that holds an optical element in an internal portion of the optical element holder, wherein the optical element holder includes a protruding feature with a contact portion that holds the optical element in the internal portion of the optical element holder. The optical device may additionally comprise the optical element, wherein an edge of the optical element includes a chamfered portion that contacts the contact portion of the protruding feature of the optical element holder to allow the protruding feature of the optical element holder to hold the optical element in the internal portion of the optical element holder.
