…manufacturing.
These utilize lower power CO2 and fiber lasers, and
increasingly, nanosecond pulsewidth diodepumped, solid-state lasers and industrial ultrafast
(picosecond pulsewidth regime) sources, as well as
excimer lasers. We now support applications
spanning precision…

nanosecond laser for laser grooving, but
now we've switched to a 1064-nm picosecond laser and perform stealth dicing. This has delivered several benefits.
First, the picosecond laser produces a
much smaller heat-affected zone than
the nanosecond laser," Zhao explained.…

Picosecond laser marking
With picosecond lasers, the pulse duration
is typically shorter than the time for heat to
flow out of the laser interaction zone, even
in metals, so peripheral thermal effects
are greatly reduced compared to nanosecond lasers. This means that a…

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

…Traditional Laser Marking
Laser marking is not a new idea - it has been used to produce various types of marks for
literally decades now in numerous industries. Carbon dioxide (CO2
) lasers, solid-state
nanosecond (called DPSS) lasers, and continuous-wave fiber lasers all…

…wires, medical products and signs. Most of these applications are serviced by Qswitched, diode-pumped, solidstate (DPSS) lasers with nanosecond pulsewidths, CO2 lasers or fiber lasers. Often these applications are highly cost sensitive, in terms of system cost and cost per mark. However, there is an…

…(DPSS) lasers with nanosecond pulse widths, CO2 lasers, or fibre lasers. These technologies are available at a reasonable cost and they support fast process throughput rates. Recently, a new class of so-called "high value" marking applications has emerged that require industrial picosecond lasers to…

…3. A CO laser with only 9W of output power produced this clean, curved cut (6 mm radius circle) in thin
glass (50 µm thick) at a feed rate of 140 mm /sec.
Laser Ablation
Laser ablation relies on a completely different mechanism to process glass than CO2 and CO lasers,
which…

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

…produce a smooth variation in surface profile, without
any cracks.
A laser with a pulse width of 700 ps, operating at
532 nm, has proved effective for this process, whereas
lasers with longer (nanosecond) pulse widths may cause
types of damage that are not acceptable. In…
