While noted improvements have taken place in the area of ceramics and metals, it is the field of polymers that has experienced an explosion in progress.

Advances in Laser Materials Processing

The unique characteristics of ultrafast lasers have rapidly revolutionized materials processing after their first demonstration in The ultrashort pulse width of the laser suppresses heat diffusion to the surroundings of the processed region, which minimizes the formation of a heat-affected zone and thereby enables ultrahigh precision micro- and nanofabrication of various materials. In addition, the extremely high peak intensity can induce nonlinear multiphoton absorption, which extends the diversity of materials that can be processed to transparent materials such as glass. Nonlinear multiphoton absorption enables three-dimensional 3D micro- and nanofabrication by irradiation with tightly focused femtosecond laser pulses inside transparent materials. Thus, ultrafast lasers are currently widely used for both fundamental research and practical applications.

Professor R. Osgood, Jr.

Laser ablation or photoablation is the process of removing material from a solid or occasionally liquid surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma. Usually, laser ablation refers to removing material with a pulsed laser , but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough. The depth over which the laser energy is absorbed, and thus the amount of material removed by a single laser pulse, depends on the material's optical properties and the laser wavelength and pulse length.

Laser interactions with materials: from fundamentals to applications

Беккер знал, что Стратмор в пять минут вызволит его из тюрьмы, но понимал, что это дело надо завершить совершенно. Арест никак не вписывался в его планы.

Она закрыла лицо руками. Дэвид не мог прийти в. - Но, Сьюзан… я думал… - Он взял ее за дрожащие плечи и повернул к. И тогда он увидел, что Сьюзан вовсе не плакала. - Я не выйду за тебя замуж! - Она расхохоталась и стукнула его подушкой.  - До тех пор, пока ты не объяснишь, что такое без воска.

Оперативные агенты сообщают последние данные о ходе выполнения поставленных перед ними задач. Банк данных АНБ - это основа основ тысяч правительственных операций. Отключить все это без подготовки - значит парализовать разведдеятельность во всем мире.

Сел. Поднял посверкивающую полуавтоматическую беретту и нацелил ее на дверь, а потом опустил себе на колени. - Сьюзан, - сказал он торжественно.  - Здесь мы в безопасности. Нам нужно поговорить. Если Грег Хейл ворвется… - Он не закончил фразу. Сьюзан потеряла дар речи.

 Да, да, - сказал он, - читайте эту благословенную надпись. Сьюзан стояла рядом, у нее подгибались колени и пылали щеки. Все в комнате оставили свои занятия и смотрели на огромный экран и на Дэвида Беккера. Профессор вертел кольцо в пальцах и изучал надпись. - Читайте медленно и точно! - приказал Джабба.

Беккер снисходительно покачал головой: - Иногда все выглядит не так, как есть на самом деле. Лицо немца стало белым как полотно. Беккер был доволен .
