Pellin Broca Prisms (PBP)
Low loss for p-polarized beam
Versions available for femto-second GVD correction
Separation of harmonic wavelengths
Angle f = 79.5 deg., Angle ?: 60 deg.
Pellin Broca prisms are constant deviation (90°) dispersing prisms. The input angle is arranged so that total internal reflection occurs at the internal face. This will provide a constant 90° deflection for the beam with dispersion. If the input beam enters the long side of the prism the longer wavelengths will be deviated less. These prisms provide a convenient way to compensate for group velocity dispersion in ultra-fast lasers or to separate harmonic wavelengths in an incoming laser beam.
