Parallel Windows
Large Wedge Windows greatly reduce or eliminate interference effects
caused by multiple reflections between front and rear surfaces of plane
windows. They are well suited for use as substrates for laser output
couplers in which the reflection from the second surface must be
completely eliminated from the gain medium of very sensitive lasers. A
pair of identical wedges are used to create an adjustable beam steering
device.
