Acoustic emission monitoring technique, an essential way to analyze pulsed laser processing

Acoustic emission (AE) monitoring is used to disclose the interplay mechanisms in pulsed laser processing of float glass. Round ablated pits and irregular formed cracks are fashioned on the float glass’s higher floor by the pulsed laser dotting. By analyzing the AE alerts, the depth of laser ablation might be assessed, and the formation of huge crack might be extracted.

A current research proves that it's possible to use AE monitoring to check the pulsed laser dotting technique of float glass, and gives an alternate for monitoring research of pulsed laser processing of different brittle supplies.

Researchers led by Prof. Yu Huang at Huazhong College of Science and Expertise (HUST), China, are fascinated by laser tremendous processing expertise and gear. Their analysis focuses on quick pulsed/ultrafast laser processing of varied hard-to-process supplies, equivalent to glass, ceramics, and composite supplies.

The work, titled “Revealing the interplay mechanism of pulsed laser processing with the applying of acoustic emission,” was printed on Frontiers of Optoelectronics on June 14, 2023.

By optimizing the laser machining high quality, exploring the interplay mechanism, and monitoring the machining course of, researchers have established a extra full stereoscopic analysis system, additional realizing the related laser machining gear manufacturing.
