Anamorphic Prism Pairs
7/11/2022
Most laser diodes produce elliptically-shaped beams with different divergence angles in the x and y axes because of the rectangular shape of the diode’s active region. However, elliptical beams have a larger focused spot size than circular beams. Anamorphic prism pairs are useful for circularizing elliptical beams.
