…by employing a
laser having output in the ultraviolet.
As laser pulse width gets into the picosecond
domain, an entirely different mechanism for
material removal comes into play, called photo
ablation. This process occurs because short
laser pulse widths lead to…

…are two
different approaches that largely eliminate the HAZ. One method is to use
a laser with output in the ultraviolet. An even better approach uses laser
pulses in the picosecond domain or shorter. Here the high peak fluence
drives multiphoton absorption stripping electrons…

ultrafast (picosecond and femtosecond) lasers yield particles hundreds of nanometers in size.
Nanosecond pulse width lasers, operating in either the green (532 nm) or ultraviolet (355 nm),
are usually employed in "bottom-up" cutting. Here, the laser enters…
