Pellin Broca Prism
Pellin Broca Prism is always used to separate the harmonics of laser beam, it can be also used to compensate for group velocity dispersion. Due to the beam enters and exits the prism at Brewster’s angle, the power loss is extremely low for P-polarized beam. The angle between input and output beam is close to 90deg.
