How to phase modulate a laser: the Pockels effect

As discussed in a previous article, the phase modulation of a laser is used in ICF (Inertial Confinement Fusion) in order to prevent any damage to the system. The goal of this article is to present how this phase modulation is usually carried out. The phase modulation is accomplished using the Pockels effect created in the so-called Pockels cells. These cells are electro-optic crystals through which the light can propagate and the phase delay is modulated by the electric voltage…
