Why Do Lasers Engrave Inside Glass Without Breaking It? (力, Pulse & Focus Explained)
Glass is brittle and easy to crack. Traditional machining damages it quickly. This limits precision manufacturing. Laser engraving solves this by modifying only the internal structure1 without stressing the surface. Lasers engrave inside glass by focusing pulsed energy to trigger optical breakdown at a precise point, creating localized micro-fracture points2 without damaging the surrounding material. […]
