Commercial use of ultrashort-pulse lasers, and femtosecond pulsed lasers in particular, continues to rise, due to the ability of these sources to cleanly ablate material or tissue with minimal heating of and damage to surrounding areas, and with negligible debris generation. Today, femtosecond lasers find use in a wide range of applications, including eye surgery, fabrication of implantable medical devices, photovoltaics scribing, surface functionalization, glass cutting, and polymer film cutting for the manufacture of displays and microelectronics. In micromachining applications, there is an especially strong demand for higher power and repetition rates to achieve the higher throughputs necessary for high-volume manufacturing. Femtosecond lasers operating in the ultraviolet (UV) are also increasingly needed to process more heat-sensitive materials or to achieve extremely high-quality results.
