…conditions of high humidity, the laser beam
can be distorted by optical absorption of fluid vapor by the laser
beam. This effect can be totally eliminated by use of a proper gas
purge.
The quality of the purge gas is an extremely important factor for
trouble-free operation…

To date, acceptable - but far from ideal - levels of weld quality and reliability using fiber laser
technology have been possible. This is because one of the defining factors for this laser is its
simple circular beam profile, which is great for cutting but less than ideal for…

(Ra < 0.5 µm) often with no need for postprocessing. In brief, as the picosecond laser
beam passes through the glass thickness it
automatically oscillates between focused and

…On the basis of sophisticated
beam scanning designs which avoid pulse overlapping effects
during target ablation and ensure homogeneous layer growth,
manufacturers can capitalize on the high laser pulse frequency
without sacrificing PLD thin-film quality [10].
