…halogen, such as ArF and XeCl - sustain laser action for only a brief period of
several nanoseconds. Other lasers, like Nd or Yb diode-pumped solid-state (DPSS) lasers, lend themselves to be operated both in CW or pulsed operation.
Other lasers, like laser diodes or OPSLs, are not suitable…

laser has an average
power of 7 W, a pulsewidth <15 ps, and a
maximum pulse repetition rate of 1 MHz.
Figure 2 shows typical marks created on
1.4301 stainless steel with this laser. While
these marks appear similar to the black
marks produced using nanosecond lasers,

…excimer laser ablation process is
essential for the predictability and safety
of the LASIK procedure. Plus, the short
(nanosecond) pulse width and short wavelength remove corneal material in a relatively cold process called photoablation.

nanosecond and USP laser (in the UV).
The nanosecond laser processed at
66 mm/sec, while the USP laser cut at
193 mm/sec. The nanosecond laser
produced a substantial HAZ - seen
as a darkening in this image - while
the USP laser produced none, and…

Laser Solution
for Your
Application.
Materials processing experts face a wide range of choices in determining
the right laser for their production needs.
Nanosecond or picosecond; ultraviolet, green or infrared; CO2, DPSS or fiber
lasers. Choosing between these lasers

longer pulse width lasers tend to process
material by substantially different means.
Many traditional applications rely on infrared
and visible Q-switched lasers, which have
pulse widths in the tens of nanoseconds
range, and which remove material via a
photothermal…

applications for ultrafast lasers, however, are in cutting using an ablative process and they do require small
spot diameters. In this case, operating the laser in burst mode, with delivering a group of 5-20 pulses with
distance of tens of nanosecond may be the best solution to reach…

few nanoseconds) pulse duration, these
factors enable precision micro-ablation of
tissue with almost no peripheral thermal
effects.
