... Another way of imposing broadband polarization control is to use a device called a Pockels cell. This device is based on a birefringent crystal that is isotropic until a voltage is applied across it. When a voltage is applied across the crystal, a birefringence, that is difference in ne and no devel ...

... In some situations we do not want a high reflectivity. In fact, we want to minimize the reflectivity as far as possible. One very effective way of reducing the reflectivity of a glass surface is to coat it with an antireflection (AR) coating (giving an ARC). A good ARC can cut the percentage of ligh ...
