If you work with applications for cutting organic light emitting diodes (OLEDs), silicon, or brittle materials, then you will be interested in this versatile laser. The Light Conversion CARBIDE femtosecond, UV module combines these key parameters: 343 nm wavelength (for specific wavelength-dependent absorption of the material or smaller attainable beam size at the focus) 30 … Continue reading
Introduction to laser cutting and welding Laser cutting is generally a fairly simple and straight-forward process. Using a high-power laser beam focused into a tight spot and aimed at the work surface, the laser energy is absorbed in the workpiece and then converted into heat. This heat in turn can cause vaporization or ablation of … Continue reading
The DeepCleave module from Holo/Or is a complete optical solution for cutting applications. There is no need for additional high NA objectives or other high cost optics. The module focuses an incident single mode laser into a tight spot with ~1.8 µm waist size along the entire Depth of Focus range (1–2 mm typical range). PN Depth … Continue reading
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 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
Laser glass cutting with ultra-short IR pulses is fast becoming a key technique for high throughput glass processing. Cutting of thick glass (> 500 µm) using this technique possesses unique challenges, as the laser energy needs to be both focused to a tight spot and spread evenly throughout the depth of the glass. To help … Continue reading
