The way in which the profile of a laser beam changes as it propagates is determined by diffraction.

Trivalent holmium ions have fluorescent properties similar to many other rare earth ions ( while yielding their own set of unique emission light lines ), and holmium ions are thus used in the same way as some other rare earths in certain laser and glass colorant applications.

The 68000 became the dominant CPU for Unix based workstations including Sun workstations and Apollo / Domain workstations, found its way into heralded computers such as the Apple Lisa and Macintosh, Amiga, Atari ST, and was used in the first generation of desktop laser printers including the original Apple Inc. LaserWriter and the HP LaserJet.

However, the introduction of the laser in the 1960s appeared to offer the possibility of a way out of the problem.

A laser printer is unable to work this way because such a large amount of data needs to output to the printing device in a rapid, continuous process.

This etching is typically done with acid, a laser, or a glass etching tool from a craft shop to provide nucleation sites for continuous bubble formation ( note that not all glasses are etched in this way ).

A faster but expensive way to measure large areas ( not details, and no obstacles ) is with a helicopter, equipped with a laser scanner, combined with a GPS to determine the position and elevation of the helicopter.

Electrolysis as a profession faced new competition in the 1990s after laser hair removal was developed and promoted as a quicker and easier way to remove hair.

Though it is technically possible to use a medical laser for scarification, this term refers not an actual laser, but rather an electrosurgical unit which uses electricity to cut and cauterize the skin, similar to the way an arc welder works.

For a start, Rick is now armed with a laser gun and bombs that can not only be placed but slid, making way for strategic bomb-placement.

In this way, each pulse of laser light results in a vertical profile of aerosol concentration within the atmosphere.

Laser scanners work the same way as pen type readers except that they use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the bar code.

The preamplifiers of the National Ignition Facility are the first step in increasing the energy of laser beams as they make their way toward the target chamber.

The first way uses photon radiation pressure to drive momentum transfer and is the principle behind solar sails and laser sails.

Microdiscectomy is a minimally invasive surgical procedure in which a portion of a herniated nucleus pulpolsus is removed by way of a surgical instrument or laser while using an operating microscope or loupe for magnification.

The deeper layers, if reshaped by a laser or cut by a microtome, will remain that way permanently with only limited healing or remodelling.

SLMs are used extensively in holographic data storage setups to encode information into a laser beam in exactly the same way as a transparency does for an overhead projector.

At the same time, development of short and ultrashort laser pulses — created by Q switching and modelocking techniques — opened the way to the study of unimaginably fast (" ultrafast ") processes.

The laser enters the eye through the pupil to illuminate the region it has been focused onto and light reflected back leaves the same way.

Because the laser beam is deflected by astronomical seeing on the way up, the returning laser light does not randomly move around in the sky as astronomical sources do.

* In the cartoon continuity ( where the life essence of a Transformer was twice referred to as a " laser core "), the only way to bestow full life was via the supercomputer, Vector Sigma, as was the case with the Stunticons and the Aerialbots.

from the early evening lights of them which had first startled Izaak to look at her in an uncousinly way, they had faded to a near-absence of color which had, possibly from her constant looking at the water, something of the light of the sea in them.

otherwise, you'll have to spend a few minutes to either attach a suitable spring clip somewhere on the press head or fit the key to a length of light chain and fasten to the bottom of the motor mount so that the key is out of the way when not in use.

When the light went their way, they went on across the street.

We discussed the candle and decided the hypothetical other bum would have left it burning to light his way to the window and because he'd have no reason to blow it out.

Guided modeling with light hand contact is the primary tool for detecting and guiding the way past unnecessary effort.

Another way to state this is that the emitting object may have a transverse velocity with respect to the observer, but any light beam emitted from it which reaches the observer, cannot, for it must have been previously emitted in such a direction that its transverse component has been " corrected " for.

In the light of the blockage concerning the entry into force of the Ban amendment, Switzerland and Indonesia have launched a “ Country-led Initiative ” ( CLI ) to discuss in an informal manner a way forward to ensure that the transboundary movements of hazardous wastes, especially to developing countries and countries with economies in transition, do not lead to an unsound management of hazardous wastes.

According to the Jewish Encyclopedia, " a comparison of the Masoretic text with the Septuagint throws some light on the last phase in the history of the origin of the Book of Jeremiah, inasmuch as the translation into Greek was already under way before the work on the Hebrew book had come to an end ...

The intrinsic property is that it reflects radiation ( including light ) in a certain way.

Second, they do so in an appealingly simple way, by dividing the world sharply between the forces of light, and the forces of darkness.

The change in height between pits and lands results in a difference in the way the light is reflected.

His attendant witnesses heavenly light in the direction of Columba, and Holy angels joins the saint in his passage to the Lord: And having given them his holy benediction in this way, he immediately breathed his last.

Once the ray either encounters a light source, or more probably once a set limiting number of bounces has been evaluated, then the surface illumination at that final point is evaluated using techniques described above, and the changes along the way through the various bounces evaluated to estimate a value observed at the point of view.

Radiosity is a method which attempts to simulate the way in which directly illuminated surfaces act as indirect light sources that illuminate other surfaces.

In 1923, Danish and Dutch scientists Christian Christiansen and Hendrik Anthony Kramers, in an analysis of formation of polymers, pointed out that such a chain reaction need not start with a molecule excited by light, but could also start with two molecules colliding violently in the traditional way classically previously proposed for initiation of chemical reactions, by van't Hoff.

The speed of light and other EMR predicted by Maxwell's equations did not appear unless the equations were modified in a way first suggested by FitzGerald and Lorentz ( see history of special relativity ), or else otherwise it would depend on the speed of observer relative to the " medium " ( called luminiferous aether ) which supposedly " carried " the electromagnetic wave ( in a manner analogous to the way air carries sound waves ).

Visible light is able to affect a few molecules with single photons, but usually not in a permanent or damaging way, in the absence of power high enough to increase temperature to damaging levels.

One way to reconcile the two theories is to assume the existence of a luminiferous aether through which the light propagates.

... this epistle is the principal and most excellent part of the new testament, and most pure evangelion, that is to say glad tidings and what we call the gospel, and also a light and a way in unto the whole scripture ...

This new rating is not a change to the stock itself-it is merely a way of calculating exposure without figuring out the compensation after each light reading.

Although the theory of special relativity forbids objects to have a relative velocity greater than light speed, and general relativity reduces to special relativity in a local sense ( in small regions of spacetime where curvature is negligible ), general relativity does allow the space between distant objects to expand in such a way that they have a " recession velocity " which exceeds the speed of light, and it is thought that galaxies which are at a distance of more than about 14 billion light-years from us today have a recession velocity which is faster than light.
