: plane/plane, concentric, confocal, etc.) along with the diameter and length of the cavity. The face of the output coupler facing into the cavity is the side with the applied partially reflective coating.
The dimensions of the optical component include parameters such as (plane/plane, concentric, confocal, etc.) in conjunction with the diameter and length of the cavity. The surface of the output coupler confronting the cavity features a partially reflective coating that has been applied.
