The first laser eye surgery dates back to approximately 30 years.

Communication in space. Laser communications systems are wireless connections through the atmosphere, The light speed is the fastest speed than anything can travel, so laser communications and laser sensing are important in mortar defense and other crucial aerospace and defense applications. Lasers are able to see through the dense foliage, and they can allow for space communication from distances measured in millions of miles, We use lasers everywhere such as in the military systems, the avionics and in submarines.

The free electron laser uses a beam of relativistic electrons passing through a periodic, transverse magnetic field to produce coherent radiation. These devices have several advantages. A resonance condition that involves the energy of the electron beam, the strength of the magnetic field, and the periodicity of the magnet determines the wavelength of the radiation. Because one medium, the electrons, provides the gain in all spectral regions, adjusting either the beam energy or the field strength tunes the wavelength easily and rapidly over a wide range. Waste energy leaves the medium as kinetic energy of the electrons at nearly the speed of light.

This difference allows lasers to focus light and energy on very small surfaces, even on far-away objects -- a unique characteristic that lends itself to various applications. Aside from their various applications, lasers are classified according to how they emit light. Their classification basis also stems from the medium or materials used as a source of light, whether gas, solid-state or diode lasers.

Он торопливо повернул выключатель. Стекла очков блеснули, и его пальцы снова задвигались в воздухе. Он, как обычно, записал имена жертв. Контакты на кончиках пальцев замкнулись, и на линзах очков, подобно бестелесным духам, замелькали буквы. ОБЪЕКТ: РОСИО ЕВА ГРАНАДА - ЛИКВИДИРОВАНА ОБЪЕКТ: ГАНС ХУБЕР - ЛИКВИДИРОВАН Тремя этажами ниже Дэвид Беккер заплатил по счету и со стаканом в руке направился через холл на открытую террасу гостиницы. - Туда и обратно, - пробормотал .

 Директор. Директор! - кричал. ГЛАВА 95 Кровь Христа… чаша спасения… Люди сгрудились вокруг бездыханного тела на скамье. Вверху мирно раскачивалась курильница. Халохот, расталкивая людей, двигался по центральному проходу, ища глазами намеченную жертву. Он где-то. Халохот повернулся к алтарю.

Она села и начала, подобно пианисту-виртуозу, перебирать клавиши Большого Брата. Бринкерхофф посмотрел на мониторы, занимавшие едва ли не всю стену перед ее столом. На каждом из них красовалась печать АНБ. - Хочешь посмотреть, чем занимаются люди в шифровалке? - спросил он, заметно нервничая. - Вовсе нет, - ответила Мидж.

В АНБ он получил кличку Джабба и приобрел репутацию полубога. Он бродил по коридорам шифровалки, тушил бесконечные виртуальные пожары и проклинал слабоумие нерадивых невежд.
