. Another class of applications uses laser ablation to process the material removed into new forms ...Cleanup date May 2007 Laser ablation 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 evaporation evaporates or Sublimation chemistry sublimates . At high laser flux, the material is typically converted to a Plasma physics 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. Fundamentals 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 . Laser pulses can vary over a very wide range ... laser ablation very valuable for both research and industrial applications. Applications The simplest application of laser ablation is to remove material from a solid surface in a controlled fashion. Laser machining and particularly laser drilling are examples pulsed lasers can drill extremely small, deep holes through very hard materials. Very short laser pulses remove material so quickly that the surrounding material absorbs very little heat, so laser drilling can be done on delicate or heat sensitive materials, including tooth enamel laser dentistry . Also, laser energy can be selectively ... of a laser to ablate a block of pure graphite , and later graphite mixed with catalytic metal . ref cite journal doi 10.1016 0009 2614 95 00825 O title Catalytic growth of single walled nanotubes by laser ..., the graphite block is placed inside an oven with a laser pointed at it, and Argon Ar gas is pumped along the direction of the laser point.

Distinguish Nuclear pumped laser A nuclear laser is a laser that would depend on the Excited state excitation of atomic Nucleus atomic structure nuclei to produce electromagnetic radiation .No such laser exists yet as of April 2011. Eugene Tkalya of Moscow State University in Russia has proposed, on 22 April 2011, a path for achieving this. Description Expand section date April 2011 Ordinary Atomic physics atomic lasers produce electromagnetic radiation when an atom or molecule drops to a lower energy level , transferring its energy to that radiation.They produce Visible light visible , Ultraviolet light ultraviolet and Infrared light infrared light, or X ray X rays , but not the very energetic Gamma ray gamma rays . To produce gamma ray lasers, researchears have studied the nuclei. A nuclear laser would produce radiation when excited nuclei would drop to unexcited states.But, as a first step to achieve a gamma ray laser, Tkalya imagined a nuclear laser which would produce visible light. To create the population inversion necessary for the laser effect, Tkalya proposes applying either a strong magnetic field of about 100 Tesla unit tesla or a strong electric field gradient of about 10 18 volts per square centimetre to nuclei of thorium . Uses A nuclear laser could be used for measuring time and for other things.
