Ultrashort laser ablation have the capability to ablate materials precisely with little or no collateral damage, even with materials that are impervious to laser energy from conventional pulsed lasers. The extreme intensities and short timescale at which ultrashort pulsed lasers operate differentiate them from other lasers such as nanosecond laser.

Published 2 November 2007 • 2007 IOP Publishing Ltd Journal of Physics D: Applied Physics, Volume 40, Number 22 2019-04-12 · The presented GHz femtosecond laser source is used with a galvanometric scanner to perform ablation experiments on copper, aluminum, and stainless steel. Specific ablation rates of 0.7, 2.3, and 1.4 (mm 3 /min)/W are reached. We demonstrated a method of fabricating three-dimensional (3D) metal structures in hydrogels with good conductivity by using femtosecond laser ablation and electroplating. The hydrogel containing Ag+ was first ablated by a femtosecond laser to form microchannels with an entrance achieving surface and then sandwiched between the anode and cathode to operate electroplating. Silver structures 2005-12-18 · Short-pulse laser ablation is promising owing to the low threshold for material removal from surfaces. In the laser-ablation process, solid material transforms into a volatile phase initiated by a 2019-10-30 · Femtosecond laser pulses far surpass the tissue interaction capabilities of other laser systems due to the unique non-linear, multiphoton interaction between fs laser-pulses and biological tissue.

RPMC Lasers offers a range of <300 picosecond, >300 picosecond, and femtosecond lasers for laser ablation, with wavelengths ranging from the UV through the IR. These pulsed lasers are available with both active and passive Q-switches The ablation geometries for the cross-sectional profiles of a laser track are presented to be a Gaussian-like distribution similar to the laser power pattern. The beam output with a diameter (ω L ) of 3 mm was emitted from the Spitfire amplifier; and the focal length (F LO ) of the objective lens is 200 mm.

Mar 16, 2021 Debye colloquium Dries van Oosten: Femtosecond laser ablation.

Femtosecond laser ablation of aluminum from low to high laser intensity has been investigated by a 2D axisymmetric hydrodynamic model. The ablations in air and in vacuum were compared, and the underlying physics mechanisms were analyzed. The RP Photonics Buyer's Guide contains 21 suppliers for laser ablation machinery.

Femtosecond laser ablation

Abstract: Thermodynamics effects generated by femtosecond laser ablation are very important. In this work, the numerical simulation of high-energy femtosecond laser ablation especially the electro-phonon coupling coefficient influence of high-energy femtosecond laser ablation on metal target was studied. Interaction of intense ultrashort laser pulses (120 fs at 795 nm) with polymer based composites has been investigated. We have found that carbon filled polymers exhibit different ultrafast ablation behaviour depending on whether the filling material is carbon black or carbon fiber and on the polymer matrix itself. 2017-09-11 · The experimental setup for the temporally shaped femtosecond laser ablation is shown in Supplementary Figure S1, wherein a conventional femtosecond pulse is temporally shaped into two subpulses 2011-11-01 · The performance of femtosecond (fs) laser intrastromal ablation was evaluated with backscattering-mode adaptive-optics multiphoton microscopy in ex vivo chicken corneas. The pulse energy of the fs source used for ablation was set to generate two different ablation patterns within the corneal stroma at a certain depth.
