residual stress in the glass. The result is a
better quality cut, stronger glass, and a
wider cut process window.
The CO laser also enables radial (freeform) glass cutting; in contrast, CO

lasers can only produce straight line cuts
because the inherently round…

…residual stress in the glass. The result is a better-quality cut, stronger glass, and a wider cut process window (FIGURE). Another important advantage is that the CO laser enables radial (free-form) glass cutting. In contrast, CO 2 lasers can only produce straight-line cuts because the inherently…

…L = 1110.17 µm
L = 269.88 µm
Fig. 2 A 270 µm deep cut (25 %) in a 1.1 mm thick glass substrate shows virtually no stress
or microcracking.
Fig. 3 CO laser cutting of 50 µm thick glass produces no
cracks or defects as compared with traditional mechanical
cutting.

…processing strategy. Before this work, despite optimization of the laser parameters, cutting
produced an asymmetrical HAZ, some burns and some debris.
For fingerprint sensor cutting, the best results were an essentially perfect cut, which produced a
sufficiently small amount of debris…

…that can cover 200 nm to 20 µm.
Common laser types
For many years, the most common CW laser was the helium neon laser, or HeNe. These low-power lasers (a few milliwatts) use an electric discharge to create
a low-pressure plasma in a glass tube; nearly all emit in the red at 633 nm. In…

and contact-free method to produce these
complex curved features. Figure 1 compares
mechanically cut and laser-cut glass.

…chemically strengthened glass, which is even
more difficult to cut mechanically, especially at economically viable speeds.
Laser glass cutting has been in use for some time in
the display industry. This is primarily accomplished with
CO

piece, together with a wider process window, for the manufacturer.
The other exciting aspect of CO lasers
in glass cutting is their ability to support
the cutting of curves. This is of…

However, one limitation in some applications is that these picosecond systems
are not completely material neutral. Cutting mixed layer substrates, such as polyimide on glass and metal on glass, often
requires an additional laser process to cut

Cutting:
Laser cutting is a mature industrial process with high flexibility, noncontact and stress free processes that produce finished parts direct
from the tool. Laser cutting is a very precise process, with excellent
dimensional stability, very…
