<td><div class="flat1">An optical isolator transmits the linearly polarized
light in one direction and stops the most of light (with any polarization)
in reverse direction. It consists of a Faraday rotator and two polarizers.
The Faraday rotator is made of magneto-optically active rod placed
inside the permanent magnet (Nd-Fe-B). The rod can be made of three
types of the magneto-optically active materials: Terbium-doped glass
(MOS-10), Terbium-gallium-garnet (TGG) crystals or Yttrium-iron-garnet
(YIG) crystals.</div>
<div class="flat1">The isolator serves for isolating a laser by attenuating
reflected and backscattered light by several orders of magnitude.
It is used when some devices have extreme sensitivity to optical feedback
which can cause intensity instabilities, frequency pulling and other
unwanted effects. </div>

isolator/rotator constructions or specify Your special wishes.</div>
