Abstract
The design and application of an uncoated sapphire crystal as a beamsplitter and output coupler of a laser resonator includes placing the crystal sufficiently close to the Brewster angle to intercept a beam from a lasing medium in a free electron laser to provide a Fox-Smith type resonator or a Michelson type resonator depending on the optical path through the crystal to enable use of high power lasers in interferometric and optical coupling measurements.
