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. This review presents progress in ultrafast laser processing, including micromachining, surface micro- and nanostructuring, nanoablation, and 3D and volume processing. Advanced technologies that promise to enhance the performance of ultrafast laser processing, such as hybrid additive and subtractive processing, and shaped beam processing are discussed.

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.

Она знала, что есть только один способ доказать свою правоту - выяснить все самой, а если понадобится, то с помощью Джаббы. Мидж развернулась и направилась к двери. Откуда ни возьмись появился Бринкерхофф и преградил ей дорогу. - Куда держишь путь. - Домой! - солгала Мидж.

Росио уверенно, по-хозяйски вошла в спальню. - Чем могу помочь? - спросила она на гортанном английском. Беккер не мигая смотрел на эту восхитительную женщину.
