co`her´ent light


n.1.(Physics, Optics) Light in which the phases of all electromagnetic waves at each point on a line normal to the direction of the the beam are identical. Coherent light is usually monochromatic, and the most common source of such light for practical uses is from a laser.

SLAC Director Chi-Chang Kao said, "Together with complementary data from SLAC's X-ray laser Linac Coherent Light Source, UED creates unprecedented opportunities for ultrafast science in a broad range of disciplines, from materials science to chemistry to the biosciences.
Xu and his team utilized the facility's Linac Coherent Light Source, the world's first hard X-ray free electron laser, to generate the first three-dimensional map of arrestin while it was linked with a GPCR.
When a wave of light reaches the apex of a cone, it diffracts and leaves the surface as coherent light [light that focuses like a laser]," Kazan said.
The classic double-slit experiment is simple to execute, requiring only a coherent light source such as a laser pointer, a screen and a plate with two thin parallel slits.
Department of Energy's (DOE) SLAC National Accelerator Laboratory scientists using SLAC's Linac Coherent Light Source (LCLS) X-ray laser found that it takes only 1 trillionth of a second to flip the on-off electrical switch in samples of magnetite, which is thousands of times faster than in transistors now in use.
Now researchers have found a way to do so using the Linac Coherent Light Source free-electron laser, the world's most powerful X-ray laser.
It's also a coherent light source, which means that the waves have a constant phase difference.
By combining light from the incoherent light source with the light from the coherent light source, the overall power level of the coherent light source in the combined light beam may be reduced while still perceiving a crisp, clear image," writes the inventor, Brett Bilbrey.
