  2. Laser ablation - Wikipedia

    en.wikipedia.org/wiki/Laser_ablation

    Laser ablation or photoablation (also called laser blasting [1] [2] [3]) 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 .

  3. Pulsed laser deposition - Wikipedia

    en.wikipedia.org/wiki/Pulsed_laser_deposition

    A plume ejected from a SrRuO 3 target during pulsed laser deposition. One possible configuration of a PLD deposition chamber. Pulsed laser deposition (PLD) is a physical vapor deposition (PVD) technique where a high-power pulsed laser beam is focused inside a vacuum chamber to strike a target of the material that is to be deposited.

  4. Pulsed laser - Wikipedia

    en.wikipedia.org/wiki/Pulsed_laser

    Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. [1] This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode.

  5. Laser ablation synthesis in solution - Wikipedia

    en.wikipedia.org/wiki/Laser_ablation_synthesis...

    Laser ablation synthesis in solution (LASiS) is a commonly used method for obtaining colloidal solution of nanoparticles in a variety of solvents. [ 1 ] [ 2 ] Nanoparticles (NPs,), are useful in chemistry, engineering and biochemistry due to their large surface-to-volume ratio that causes them to have unique physical properties. [ 3 ]

  6. Surface-enhanced laser desorption/ionization - Wikipedia

    en.wikipedia.org/wiki/Surface-enhanced_laser_de...

    Samples spotted on a SELDI surface are typically analyzed using time-of-flight mass spectrometry. An irradiating laser ionizes peptides from crystals of the sample/matrix mixture. The matrix absorbs the energy of the laser pulse, preventing destruction of the molecule, and transfers charge to the sample molecules, forming ions.

  7. Laser drilling - Wikipedia

    en.wikipedia.org/wiki/Laser_drilling

    A flash lamp pumped Nd:YAG laser normally has a pulse duration on the order of hundreds of microseconds to a millisecond, peak power in the order of sub MW/cm 2, and material removal rate of ten to hundreds of micrometers per pulse. For machining processes by each laser, ablation and melt expulsion typically coexist. [citation needed]

  8. Synthesis of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_carbon_nanotubes

    In laser ablation, a pulsed laser vaporizes a graphite target in a high-temperature reactor while an inert gas is led into the chamber. Nanotubes develop on the cooler surfaces of the reactor as the vaporized carbon condenses. A water-cooled surface may be included in the system to collect the nanotubes.

  9. Nd:YAG laser - Wikipedia

    en.wikipedia.org/wiki/Nd:YAG_laser

    The Nd:YAG laser is the most common laser used in laser designators and laser rangefinders. During the Iran–Iraq War, Iranian soldiers suffered more than 4000 cases of laser eye injury, caused by a variety of Iraqi sources including tank rangefinders. The 1064 nm wavelength of Nd:YAG is thought to be particularly dangerous, as it is invisible ...
