The primary manufacturers of excimer laser light sources in the 1980s were Lambda Physik ( now part of Coherent, Inc .) and Lumonics, but since the mid-1990s Cymer Inc. has become the dominant supplier of excimer laser sources to the lithography equipment manufacturers.

* Coherent perfect absorber, a device which absorbs coherent light and converts it to some form of internal energy such as heat or electrical energy

* Coherent ( company ), a company specializing in equipment to make and measure coherent light

Coherent light, the principle behind lasing, was first predicted by Einstein in 1916, but not created until 1954 by Charles H. Townes with the maser.

* Coherent backscattering is observed in random media ; for visible light most typically in suspensions like milk.

Coherent light generally must be treated with Jones calculus because the latter works with amplitude rather than intensity of light.

Coherent control is a quantum mechanical based method for controlling dynamical processes with light, employing quantum interference phenomena which are controlled by shaping the phase of laser pulses.

Coherent emission from a laser dye-doped tandem SM-OLED device, excited in the pulsed regime, has been demonstrated.

By contrast, at the 2004 Optical Society of America " Conference on Lasers and Electro-Optics ," held in San Francisco, California, one company ( Coherent, Inc .) announced 45 watt continuous wave single-mode emission from an optically pumped VECSEL.

However, the concept of coherent states has been considerably generalized, to the extent that it has become a major topic in mathematical physics and in applied mathematics, with applications ranging from quantization to signal processing and image processing ( see Coherent states in mathematical physics ).

Each of these properties may lead to generalizations, in general different from each other ( see the article ' Coherent states in mathematical physics ' for some of these ).

This more commoditized hardware approach also led DG to develop NUMA servers that added a memory-coherent interconnect ( Scalable Coherent Interconnect ( SCI )) to " standard high-volume " x86 motherboards sourced from Intel.

Historically there have been other variants including AIX ( small ), AIX ( big ) and Coherent, which all vary significantly from the common format.

Coherent quotes from newspaper articles are often woven into the biographies as well, calling into question the strict separation between them and the " Newsreel " sections.

As a consequence, many licensing agreements and start-up firms have arisen from research conducted at the institute, e. g. Lambda Physik ( today part of Coherent ), DeveloGen ( today part of Evotec ) and Evotec.

Coherent though bizarre his speech may be, Josef Tock does not recover from his event, but expires right when the baby is born.

The Mark Williams Company was a small software company in Chicago, Illinois ( later moved to Northbrook, Illinois ) that created Coherent, one of the first Unix-like operating systems for IBM PCs and several C programming language compilers.

Examples of facilities operating on the SASE FEL principle include the Free electron LASer ( FLASH ) in Hamburg, the Linac Coherent Light Source ( LCLS ) at the SLAC National Accelerator Laboratory, the European x-ray free electron laser ( XFEL ) in Hamburg, the SPring-8 Compact SASE Source ( SCSS ), the SwissFEL at the Paul Scherrer Institute ( Switzerland ) and, as of 2011, the SACLA at the RIKEN Harima Institute in Japan.

The IEEE Std 1596-1992, IEEE Standard for Scalable Coherent Interface ( SCI ) was approved by the IEEE standards board on March 19, 1992.

The Coherent operating system was a Version 7 Unix clone by the now-defunct Mark Williams Company, originally produced for the PDP-11 in 1980.

Coherent was able to run on most Intel-based PCs with Intel 8088, 286, 386, and 486 processors.

Like a true Unix, Coherent was able to multitask and support multiple users.

A Zilog Z8000 port of Coherent was also used by the canceled Commodore 900 system.

Coherent was not Unix ; the Mark Williams Company had no rights to either the Unix trademark or the AT & T / Bell Labs source code.

The delegation included Dennis Ritchie, who concluded that " it was very hard to believe that Coherent and its basic applications were not created without considerable study of the OS code and details of its applications " and " that looking at various corners peculiarities, bugs, etc.

Being that Coherent was a commercially available package and Linux was distributed freely on the Internet via their GNU public license, Coherent sales plummeted and Mr. Swartz had no choice but to cease operations in 1995.

* Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by the radiating field.

Coherent backscattering, an enhancement of backscattering that occurs when coherent radiation is multiply scattered by a random medium, is usually attributed to weak localization.

Coherent predates both MINIX and Linux by many years.

Invited paper, selected for publication in the book: " Coherent Lightwave Communications ", by P. S. HENRY et S. D. PERSONICK, IEEE Press, N. Y. 1989.

Coherent waves that travel along two different paths will arrive with phase shift, hence interfering with each other.

A group then organized to create a system aimed directly at this need, which eventually led to Scalable Coherent Interconnect.

* 5. 1 Music Disc, an extension to the red book standard that uses DTS Coherent Acoustics 5. 1 surround sound

* Coherent anti-Stokes Raman spectroscopy ( CARS ) is a recent technique that has high sensitivity and powerful applications for in vivo spectroscopy and imaging.

Scalable Coherent Interface ( SCI ) is an IEEE standard defining a directory based cache coherency protocol to avoid scalability limitations found in earlier multiprocessor systems.

SCI, for Scalable Coherent Interface, is a high-speed interconnect standard for shared memory multiprocessing and message passing.

His results became the basis of his habilitation on " Coherent Radiation of Electrons in the Synchrotron Accelerator ", defended in 1951.

They began investing in the development of a system based on a cache-coherent non-uniform memory architecture ( ccNUMA ) and leveraging Scalable Coherent Interconnect.
