Voigt Effect

From Wikipedia, the free encyclopedia

The Voigt Effect, sometimes termed magnetic birefringence or magnetic double refreaction, is a magneto-optical phenomenon whereby the polarization of light may be rotated when passed through a vapor cell immersed in a magnetic field directed perpendicular to the beam direction.

This effect is utilized in Voigt filters, a type of Atomic line filter. In this circumstance, the Voigt Effect makes the vapor cell act as a half wave plate.
