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.

But they then borrowed the carrier concept and a laser from the radar research; the laser was a much better source of the coherent light needed for holography, and the oblique exposure added depth to the image.
Later, in the 1990s, Claudio Pellegrini and collaborators proposed to extend free-electron lasers to the X-ray regime--a hugely ambitious concept that was ultimately proven with the construction of the Linac Coherent Light Source (LCLS) by the U.
Of final interest is that this energy uncertainty is intricately tied to the fact that the absorption took place due to a coherent light source.
2 [micron]m for panel A to 115 [micron]m for panel E, see figure caption for the other parameters; panel F is the reconstructed image as the hologram is recorded with a completely coherent light source.
OPV 302 VCSEL has been chosen since it is a widely available coherent light source.
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.
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.
Thomas Furness, a professor at the University of Washington, recognized that every material exhibited a unique light signature when stimulated by visible and invisible structured coherent light sources.
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.
They cover nanoscale metallo-dielectric coherent light sources, optically pumped semiconductor photonic crystal lasers, electrically pumped photonic crystal lasers: laser diodes and quantum cascade lasers, photonic-crystal vertical-cavity surface-emitting lasers (VCSEL), III-V compact lasers integrated onto silicon-on-insulator (SOI), semiconductor micro-ring, and nonlinearity in semiconductor micro-ring lasers.
