Abstract

A simple co-axially excited pulsed CO₂ laser has been developed for the application of micro-machining. The laser tube is made by a ceramic pipe with metal electrodes at both ends, and the laser tube works as a switch. The output energy of 1 mJ to 40 mJ were used for the micro-machining such as micro-drilling of Pori-Imid circuit board and marking on the glass substrate.
