Materials: Calcite, or
a-BBO
crystal.
Optically cemented structure.
High
extinction ratio ( > 100,000:1
) over an extremely
large range of wavelength.
Large
splitting angle between the two orthogonally
polarized beams ( 45o
for Calcite, 60o
for α-BBO).
Both output beams are at normal incident with the
corresponding output face.
Suitable for low and medium power applications.
