Laser Output Couplers
Laser Output Couplers are designed for use as resonator
mirrors for low, medium and high power lasers. They divide an incident,
monochromatic beam into reflected and transmitted components with the
specified intensity ratio. Substrates are available with plano/plano,
plano/concave and plano/convex surfaces. They are coated on one side
with an all dielectric, partial reflection coating, and on the reverse
side with a high efficiency, narrowband, anti-reflection coating.
