Cladding Modes - Definition and Applications

Cladding modes are the regions or modes in optical fibers that are not restricted to the region around the core of the fiber. More specifically, cladding modes are regions in which the intensity of distribution is not restricted to the region in and around the fiber core.

Collimator - Definition and Applications

Collimator is a device used for changing the direction of a light diverging from a point source into a parallel beam. The collimation of light is necessary to make spectroscopic measurements.

An Introduction Doppler Cooling

Doppler cooling is the laser based cooling of small particles, such as ions and atoms, which are trapped during the cooling process. It also involves the spontaneous emission of photons, which generate velocity-dependent light forces through the Doppler effect.

Optical Dispersion - Principle and Applications

Dispersion is the process of describing the characteristics of light waves and their interaction with a medium so that the group and phase velocities of the light propagating the medium depend on the optical frequency.

B-Integral - Definition and Significance

B-Integral is defined as the measure of the non-linear phase shift of light in devices like amplifiers. B-Integral is a term that is specific to non-linear optics. The non-linear shift of the laser system along the optical axis is equal to the B-Integral of the laser beam.
