Glass Cutting with Ultra-Short IR Laser Pulses

Laser glass cutting with ultra-short IR pulses is now a key technique for high throughput glass processing. Cutting thick glass (>500 um) using this technique possesses unique challenges. Specifically, this technique requires focusing the laser energy to a tight spot and spreading the beam evenly throughout the glass depth. To learn more about several solutions … Continue reading

Transforming Multi-Mode Laser Beam into Narrow Ring

Transforming the beam of a highly multi-mode laser into a narrow ring (annular shape) with almost single mode diffraction-limited ring width is a potentially useful technique for certain material processing applications, such as drilling and cutting. Holo/Or has published an experimental demonstration of their unique diffractive method of doing this transformation. For an article on … Continue reading
