Visible and UV lasers with nanosecond pulse durations, diffraction-limited beam quality and high pulse repetition rates have demonstrated an ability to machine a wide variety of materials with sub-micron precision and sub-micron-sized heat-affected zones. Manufacturing applications for these lasers include orifice drilling in fuel injection components and inkjet printers, micro-milling of micromolds, via hole drilling in printed circuit boards and silicon machining. Narrow line width UV is used for the fabrication of fiber Bragg gratings. Results achieved with copper vapor lasers (CVL) and diode-pumped solid state lasers will be presented. Recent advances in higher power, compact CVLs are opening new possibilities for manufacturing with this class of laser. |
