Pellin Broca Prism
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.
