The Prophylactic Effect of Dexmedetomidine 0.008% Versus Brimonidine 0.2% on IOP Elevation After Nd: YAG Laser Capsulotomy. [PDF]

open access: yesPharmacol Res Perspect
ABSTRACT Posterior capsule opacification (PCO) is a common post‐cataract surgery complication treated with Nd:YAG laser posterior capsulotomy, which may cause intraocular pressure (IOP) spikes and threaten vision. Brimonidine and apraclonidine are widely used to prevent such elevations.

Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]

open access: yes, 2010
One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.

Analysis of hybrid Nd:Yag laser-MAG arc welding processes. [PDF]

open access: yes, 2011
In the hybrid laser-arc welding process, a laser beam and an electric arc are coupled in order to combine the advantages of both processes: high welding speed, low thermal load and high depth penetration thanks to the laser; less demanding on joint ...

Direct keyhole laser welding of aluminum alloy AA5754 to titanium alloy Ti6Al4V [PDF]

open access: yes, 2014
The tensile strength of direct AA5754/Ti6Al4V joints performed by high speed Yb:YAG laser welding is found to be determined by morphology and phase content of dissimilar interface formed between contacting Al-rich and Ti-rich melted zones. Three types of
