coherent radiation x
coherent radiation
Radiation in which the phase relationship between any two points in the radiation field has a constant difference, or is exactly the same in either the spatial or the temporal mode throughout the...
noncoherent radiation
Radiation having waves that are out of phase in space and/or time.
spatially coherent radiation
The correlation of radiation between the phases of monochromatic radiation emanating from two separate points.

laser dye
Class of organic dyes that emit coherent radiation over a wide spectral range.
laser dye
Class of organic dyes that emit coherent radiation over a wide spectral range.
partial coherence theory
Totally coherent radiation is produced by a purely monochromatic point source. In the real world the energy will have a limited bandwidth and the point source will subtend some angle resulting in...
Q-switched pulse
A laser output that occurs when the cavity resonator Q is first kept very low, using rotating mirrors or saturable absorbers, so that the population inversion achieved is greater than usual. A high...
superradiance
Directional and coherent radiation pulses that result from an ensemble of coherently prepared states in an optical medium.
term coherence
A synonym for spatial coherence. See spatially coherent radiation.
