Description

Détails

Output coupler (OC) is a partially reflecting dielectric mirror used in laser cavity. It has a function to transmit a part of intracavity optical power in order to get a lasing. Output couplers listed below can be found in stable resonators, as they have a spatially constant reflection/transmission (R/T) value, which is the main property of such kind of mirror. Such cavity's parameters as pump power threshold, maximum output power and laser efficiency highly depends on R/T ratio of output coupler. Thus choosing a right output mirror for a cavity design is quite a crucial moment. For user's convenience Laserand maintains commonly used output couplers for high intensity intracavity use. Rear surface is antireflective coated in order to minimize Fresnel reflections. Concave mirrors help to maintain TEM00 spatial mode within the resonator while wedged mirror deflect Fresnel reflection that could be amplified within resonator and form secondary (parasitic) pulse.
