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 ]
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 .
In this method, the aim is to reproduce the conditions prevailing in the arc discharge and laser ablation approaches, but a carbon-containing gas is used instead of graphite vapors to supply the necessary carbon. Doing so, the growth of SWNT is more efficient (decomposing the gas can be 10 times less energy-consuming than graphite vaporization).
Asteroid laser ablation is a proposed method for deflecting asteroids, involving the use of a laser array to alter the orbit of an asteroid. Laser ablation works by heating up a substance enough to allow gaseous material to eject, either through sublimation (solid to gas) or vaporization (liquid to gas). For most asteroids this process occurs ...
Laser ablation electrospray ionization (LAESI) is an ambient ionization method for mass spectrometry that combines laser ablation from a mid-infrared (mid-IR) laser with a secondary electrospray ionization (ESI) process. The mid-IR laser is used to generate gas phase particles which are then ionized through interactions with charged droplets ...
Laser ablation is not recommended for in vivo, as the potential damage from laser was too high. High cost of operation, and extensive operating time narrowed its accessibility for cell studies. [4] Recently, laser ablation was applied with ICP-MS to develop LA-ICP-MS analysis technique. In which utilizes the precision and ability to change ...
Design of plasmonic nanolaser has become one of the most effective technology methods for laser miniaturization at present. [35] A little bit different from the conventional lasers, a typical configuration of plasmonic nanolaser includes a process of energy transfer to convert photons into surface plasmons. [ 10 ]
That is, SILEX uses a separation nozzle, modified by a laser and profiting from selective repression of cluster formation ("condensation"). For that, the CO 2 laser needs at least 20 MW. With a Raman shift of 354.3 cm −1 and a CO 2 laser wavenumber of 982.1 cm −1 (10R30 line), one receives 627.8 cm −1.
