| Pellin Broca Prism can be used to separate the
harmonics of a laser beam or compensate for group velocity dispersion.
The light enters and exits the prism near Brewster’s angle, which
minimizes reflection losses in P-polarized light. Since the beam
undergoes one total internal reflection before exiting the prism,
the angle between the input and exit beams is 90° plus a small
angle due to dispersion. The dispersion is less for longer wavelengths.
As Pellin Broca Prism is rotated about point A, the selected wavelength,
which is deviated by 90°, is changed without changing the geometry
or relative positions of the input and output beams.
