Modulators for active Q-switching lasers rely on an effect in which crystals lacking inversion symmetry become birefringent in linear proportion to the magnitude of one of these.
Particles of dielectric materials may be separated in a fractionation method that uses a nonuniform one of these. Band-bending occurs because it varies linearly in a depletion layer. Symmetric top molecules undergo line-splitting in their microwave spectrum due to the application of one of these. Modulators for active Q-switching lasers rely on an effect in which crystals lacking inversion symmetry become birefringent in linear proportion to the magnitude of one of these. Its flux through a surface is proportional to enclosed charge, and its curl is equal to the negative time partial of the magnetic field. Its magnitude is proportional to one-over-r for a line charge, and it is proportional to one over r squared for a point charge. For 10 points, name this vector field given in units of volts per meter.
