For applications in which it is necessary
to equalize the energy density across an expanded laser beam,
the Flat-Top Apodizer Plate utilizes a plano-convex, neutral
gray glass lens cemented against a plano-concave, clear glass
lens. The result is a plane-parallel plate with a radially-varying
neutral attenuation. With a correctly expanded beam, this combination
produces a "flat-top" energy distribution from a Gaussian
beam, with ~35% of the original laser power retained. Antireflection
coatings are not available. |
