Micromachining Transparent Materials by Femtosecond Laser.
The Review of Laser Engineering, 1999 We used 790-nm, 130-fs laser pulses for micromachining transparent materials including acrylic resin, quartz, diamond, and polyvinyl chloride. Using this technique, even 20 mm thick acrylic resin could bedrilled in 15 minutes, while a precise cut 20μm in width was produced in acrylic resin 0.5 mm thick.
