A solid with a structure that exhibits a basically symmetrical and geometrical arrangement. A crystal may already possess this structure, or it may acquire it through mechanical means. More than 50 chemical substances are important to the optical...
lithium niobate (LiNbO
A crystalline ferroelectric material used primarily as a substrate and an active medium for thin-film optical modulators and switches. It possesses very high electro-optic and piezoelectric coefficients.
optical parametric oscillator (OPO)
A laser-pumped crystal with nonlinear optical properties that generates coherent light whose output can be tuned continuously over a variety of infrared and visible wavelengths.
A device used to rapidly change the Q of an optical resonator. It is used in the optical resonator of a laser to prevent lasing action until a high level of inversion (optical gain and energy storage) is achieved in the lasing medium. When the...
optical path difference (OPD)
For a perfect optical system, the optical path, or distance, from an object point to a corresponding image point will be equal for all rays. In near-perfect systems, slight differences will exist between rays resulting in an optical path difference,...
See acousto-optic modulator; electro-optic modulator.
