WebIn physics, photon-induced electric field poling is a phenomenon whereby a pattern of local electric field orientations can be encoded in a suitable ferroelectric material, such as perovskite. The resulting encoded material is conceptually similar to the pattern of magnetic field orientations within the magnetic domains of a ferromagnet, and ... WebThe Pockels effect (or linear electro-optic effect) is an electric field-induced linear birefringence or anisotropic change in the refractive index of the material. The Pockels effect can be used in two modes. When the applied electric field is normal to the direction of propagation of the incident light, the transverse Pockels effect is said ... WebWe show that thermally induced birefringence in an electro-optical crystal can play an important role in Q-switched Nd:YAG lasers with a high average power output. A compensation of the thermal effects in both active-element and electro-optical crystals is achieved by employing two identical Pockels cells instead of one, with a π/2 polarization … howa mountain rifle
