electric CO laser
An electrically excited laser having carbon monoxide as the lasing material and in which lasing occurs in a partial inversion between adjacent, vibrational fields. Vibrational energy is cycled...
electro-optic effect
The change in the refractive index of a material under the influence of an electrical field.
electro-optic modulator
An electro-optic modulator (EOM) is a device used to modulate the amplitude, phase, or polarization of light waves using an external electrical signal. Electro-optic modulation is a fundamental...
electromagnetic radiation
Radiation emitted from vibrating charged particles. A combination of oscillating electrical and magnetic fields that propagates through otherwise empty space with the velocity of light. This constant...
electron optics
The control of free electron movement through the use of electrical or magnetic fields, and use of this electron movement in research investigation of electronic diffraction phenomena, directly...
electrophoresis
The movement of particles or ions in a solution toward the electrode having the opposite sign because of the application of an electrical field.
electrostatic charge
The effect produced by electrical charges or fields alone, without interaction with magnetic influence.
