For purposes of delineating the metre, the BIPM currently considers the HeNe laser wavelength to be as follows: with an estimated relative standard uncertainty ( U ) of.

For example, a typical helium-neon ( HeNe ) gas laser has a gain bandwidth of approximately 1. 5 GHz ( a wavelength range of about 0. 002 nm at a central wavelength of 633 nm ), whereas a titanium-doped sapphire ( Ti: Sapphire ) solid-state laser has a bandwidth of about 128 THz ( a 300 nm wavelength range centred around 800 nm ).

For example, it should not matter whether one measures the distance between the Great Pyramids of Giza by laser rangefinding, by satellite imaging, or with a meter stick-in all three cases, the answer should be approximately the same.

For example, the accuracy of laser rangefinding measurements is based on the scientific understanding of lasers, while satellite pictures and meter sticks rely on different phenomena.

For example, the expanding profile of a laser beam, the beam shape of a radar antenna and the field of view of an ultrasonic transducer can all be analysed using diffraction equations.

For example, if two slits are separated by 0. 5mm (), and are illuminated with a 0. 6μm wavelength laser (), then at a distance of 1m (), the spacing of the fringes will be 1. 2mm.

For some events they can be made in extended forms without a frame at all, but only a long parallel rank of laser beams yet are still called laser harps.

For example, a one-milliwatt laser pointer exerts a force of about 3. 3 piconewtons on the object being illuminated ; thus, one could lift a

For instance, laser microscopy focused on biological applications uses ultrashort pulse lasers, or femtosecond lasers, in a number of techniques labeled as nonlinear microscopy, saturation microscopy, and multiphoton fluorescence microscopy.

For technical applications such as laser mirrors, the reflective coating is typically applied by vacuum deposition on the front surface of the substrate.

For example, there are many common lasers ( e. g., dye lasers, carbon dioxide lasers ) where the laser medium consists of complete molecules, and energy states correspond to vibrational and rotational modes of oscillation of the molecules.

For a time an interpreter ( sometimes referred to as a RIP for Raster Image Processor ) for the PostScript language was a common component of laser printers, into the 1990s.

For example, one does not buy " Laser Vision ", but the effect " Energy Blast ", and specifies that it is a laser emitted by the hero's eyes.

For example, graphical wireframes on top of a laser printer would explain how to change the paper tray.

For example, applications of high-energy laser weapons and lidars require precise knowledge of how much transmitted power actually illuminates the target.

For example, an ultraviolet laser that emits at a wavelength of 308 nm will have a lower divergence than an infrared laser at 808 nm, if both have the same minimum beam diameter.

For an electromagnetic wave, the coherence time is the time over which a propagating wave ( especially a laser or maser beam ) may be considered coherent.

For applications that did not require impact ( e. g., carbon-copy printing ), the inkjet was superior in nearly all respects: comparatively quiet operation, faster print speed, and output quality almost as good as a laser printer.

For years laserprinters have been the popular choice, however line matrix printers have improved technological aspects and now claim to hold significant benefits over laser printers in terms of energy savings, cost per page, reliability in industrial environments and media flexibility ( multipart forms, oversize media, peel off labels, cloth, or card stock ).

For proteomic study, more recent techniques such as matrix-assisted laser desorption / ionization ( MALDI ) have been employed for rapid determination of proteins in particular mixtures and increasingly electrospray ionization ( ESI ).

For larger stones, the doctor may also use the extra tube in the ureteroscope to extend a flexible fiber that carries a laser beam to break the stone into smaller pieces that can then pass out of the body in the urine.

For output, it used the Apple LaserWriter, a PostScript laser printer.

For instance, the accuracy of land-survey distance measurements when using a laser rangefinder might be 1 millimeter per kilometer of distance ; this could be expressed as “ Accuracy = 1 ppm .”< ref > This is a simplified explanation.

For instance, the Ur-Quan Dreadnought has a powerful main gun and the ability to launch independent fighters ; while the Mmrnmhrm Transformer has the ability to change between two forms, a slow but quickly-turning one with a short-range laser as its main weapon, and the other quick but slowly-turning with long-range guided missiles.

For, with a single exception, nothing had happened to them.

For Tom Horn, it turned out, had a number of rancher and cowboy witnesses ready and willing to swear with straight faces that he had been in Bates Hole the day of the killing.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

For several months now, Jack Carter, a big overgrown boy of fifteen with a fuzzy, pimpled face and greenish catlike eyes with a lot of red in them, had been haunted by a dream, a vision, of a Woman.

For Mr. Taylor's Images And Reflections she made some diaphanous tents that alternately hide and reveal the performer, and a girl's cape lined with grass.

For the family is the simplest example of just such a unit, composed of people, which gives us both some immunity from, and a way of dealing with, other people.

For several generations much fiction has appeared dealing with the steprelationship.

For the President had dealt with the matter humbly, in what he conceived as the democratic way.

'', and `` Too Marvelous For Words '' ( all with Richard Whiting ) ; ;

William Wimsatt and Cleanth Brooks, it seems to me, have a penetrating insight into the way in which this control is effected: `` For if we say poetry is to talk of beauty and love ( and yet not aim at exciting erotic emotion or even an emotion of Platonic esteem ) and if it is to talk of anger and murder ( and yet not aim at arousing anger and indignation ) -- then it may be that the poetic way of dealing with these emotions will not be any kind of intensification, compounding, or magnification, or any direct assault upon the affections at all.

For some time, despondency in some Northern quarters had been displayed in two ways -- an eagerness for peace and a dissatisfaction with Lincoln.

For if Serenissimus made the sign of the Cross with his right hand, and meant it, with his left he beckoned lewdly to any lady who happened to catch his eye.

For those little men with the short whiskers, shaven polls, and top knots Suvorov reserved a special esteem.

For some reason, none of them were impressed with the territorial capital.

For example, he captured some persons from York County, who with teams were taking to Philadelphia the furniture of a man who had just been released from prison through the efforts of his wife, and who apparently was helpless to prevent the theft of his household goods.

For as his companions gradually dissolve back into a state of primitive confrontation with elemental necessity, as they lose all the appanage of their acquired culture, he is overcome by the feeling that he is at last being confronted with the essence of mankind.

`` For six years my father had had to do too much commanding and convincing, '' writes the narrator, `` not to understand that man begins with ' the other ' ''.

For a dawning sense of illumination occurs in consequence of two events which, as so often in Malraux, suddenly confront a character with the existential question of the nature and value of human life.

In his recent book, Hurray For Anything ( 1957 ), one of the most important short poems -- and it is the title poem for one of the long jazz arrangements -- is written for recital with jazz.

For a particularly fabulous room which houses a collection of fine English Chippendale furniture, fabric wall panels were embroidered with a typically Chinese-inspired design of this revered Eighteenth Century period.

For the first time in history the entire world is dominated by two large, powerful nations armed with murderous nuclear weapons that make conventional warfare of the past a nullity.
