Abstract
A large number of passes of pump light through an active mirror in a solid state disk laser is realized using a pair of coupled imaging systems, where the optical axes of imaging systems are not coincident. Two imaging systems are optically coupled, so that an image of the first imaging system is an object of the second imaging system, and vice versa. An active mirror is disposed at the object or image plane, or at the focal plane of any one of the coupled imaging systems, where the position of the reflected pump beam during the multi-reflection between the first and second imaging systems is substantially unchanged.
