Picosecond Lasers for High-Quality Industrial Micromachining
Just as CW and quasi-CW lasers have revolutionized the materials processing world, picosecond lasers are poised to change the world of micromachining. The use of picosecond lasers in micromachining was ushered in more than three decades ago because various millisecond and, later, nanosecond lasers had proved that pulsed lasers offer new capabilities.
Today, laser pulses in the millisecond to nanosecond regime are being used for drilling holes in wafers, cutting thin sheet metal and scribing...
