Abstract: The present disclosure provides examples of a laser-based material processing system for liquid-assisted, ultrashort pulse (USP) laser micromachining. An example material processing application includes drilling thru-holes or blind holes in a nearly transparent glass workpiece (substrate) using parallel processing with an n x m array of focused laser beams. Methods and systems are disclosed herein which provide for formation of high aspect ratio holes with low taper in fine pitch arrangements.
