Cutting glass with no microcracks.
The reason glass laser cutting fails is heat. Gudetech avoids it: picosecond and UV cold processing remove material before heat can spread, so brittle and coated glass come off with no heat-affected zone, no edge breakage and chipping under 5 microns.
Heat is what cracks the glass.
A hot beam dragged through glass leaves a heat-affected zone of thermal stress, the microcracks that fail a part later in the field or on the drop test. Cold processing sidesteps the problem entirely. Picosecond pulses and short-wavelength UV deliver their energy faster than heat can conduct away, removing material with a clean edge instead of a thermally damaged one. That is what lets Gudetech cut UTG, sapphire, automotive and solar glass at production speed without giving up yield.
Clean edges, every sheet.
Ultrafast pulses, no heat build-up
Picosecond pulses are short enough that energy is delivered before heat spreads into the glass. The material is removed cleanly with effectively no heat-affected zone, so there is no thermal stress to seed cracks at the cut.
No edge breakage on brittle glass
Green and UV cold processing frost, drill and remove coatings without the thermal shock that breaks or explodes brittle and tempered sheets. Sensitive glass keeps its yield through processing.
Chipping under 5 microns
Cold cutting comes off with no taper, no burrs and chipping of 5 microns or less, so cover glass, sapphire and automotive glass keep the edge strength that survives handling and drop tests.
Coated and Low-E glass, intact
Cold processing removes coatings selectively and marks surfaces without damaging the coatings around them, so Low-E and solar glass keep their performance after processing.
