Taking place in Dresden, Germany from 7th to 10th June 2022 is the 23rd International Symposium on Laser Precision Microfabrication, LPM 2022.
As part of the proceedings, Oxford Lasers will be presenting a poster paper with their project partner; Daxsonics. The poster: Multibeam ultrafast laser processing of a piezoelectric ceramic for ultrasound medical imaging, will showcase some of the work from the Innovate UK Eureka project PA64 (contract No 105609) and from the Canadian NRC-IRAP project No 937854.
Partial Abstract
Despite the term ultrafast being used to describe laser micromachining processes by ultra-short pulse durations, it is commonly accepted that these processes are frequently time consuming. In this work, we have processed a heat sensitive piezoelectric ceramic material, lead zirconate titanate (PZT). PZT is an ideal material for constructing high-frequency (high-resolution) ultrasound probes which require patterned features at micron level accuracy. These can be used to develop and enhance novel endoscopy-driven surgical procedures by providing real-time ultrasound imaging.
