…laser cut glass can typically
withstand two to three times as much force as mechanically cut glass.
Figure 1. Comparison of mechanically cut (left) and laser cut (right) glass. The mechanically cut glass shows
significant residual stress, and substantial debris from the cutting

…Corning's Gorilla Glass, Asahi's
Dragontrail and Schott's Xensation are
examples of this. The thickness of this
strengthened layer typically runs tens of
microns deep.
Traditional mechanical glass cutting can lead to microcracks and debris.
Laser glass cutting, based on…

…rounded cuts and
contours, and even cutouts.
Typically, these requirements translate into a cutting kerf width of only 25 µm, and a process
affected zone in the tens of micrometers range. This level of precision precludes virtually all
traditional mechanical cutting methods.…

Cutting through transparent solder masks (because these darken when heated)
Cutting through brittle layers, such as ceramics, glass or composite (including glass fibers),
and when there is a requirement to keep any chips formed smaller than a few tens of
microns

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…

…>320 µJ cut materials from 0.1 mm to >2 mm thick in a single pass. Additionally, the ultrashort pulse nature of Monaco allows layered or coated glass and sapphire to be processed with little or no heat affected zone. Monaco SmartCleave further expands the options for glass and film cutting to enable…

…mechanical cutting leaves significant mechanical stress in the finished edge. (In fact, it becomes difficult to use mechanical cutting with substrates below about 1 mm in thickness because the glass is so easily broken.) To prevent further cracking or breaking of the glass after the original cut, it…

glass is more difficult to cut than standard glass, which has posed some difficulties for manufacturers.
The traditional mechanical glass
cutting method involves making an initiation scribe (a limited depth cut), followed by mechanical…

…and glass
thicknesses up to 10 mm.
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
