ABSTRACT:
An optical output controlling method according to the present invention is employed in an optical system in which a polarized light is illuminated on a magneto-optical material, and in which the light reflected by the magneto-optical material is passed through a polarization beam splitter and then detected through an analyzer. An optical output can be adjusted by rotating the polarization beam splitter. In consequence, the Kerr rotation angle caused by the magneto-optical material can be increased, and the carrier to noise ratio can be thereby improved.
