…the laser beam onto the
ceramic surface in real time, in order to compensate
for package height variations. Because of their more
reliable interaction with ceramic materials, DPSS lasers
based on Nd:YAG, which offer high pulse energies and
relatively long pulses, are often…
…manufacturing scientific ultrafast lasers have focused almost exclusively on achieving leading-edge performance (like high peak power or short pulse duration), often using advanced and therefore less-proven designs. In contrast, industrial lasers have long been designed for a cost-conscious…

Femtosecond laser processing
The process requirements mentioned
above call for laser pulse widths in the
femtosecond range. Femtosecond pulses
enable new machining qualities that result

needed to create ultrashort pulses. As a
result, the shortest laser pulses are typically emitted by Ti:sapphire lasers.

…hazardous lithography chemicals. Because of these benefits, CO 2 lasers have been used extensively for drilling vias in microelectronics packaging applications for some time. However, the long infrared wavelength of CO 2 lasers limits their minimum focused spot size (due to diffraction). The result…

What started with crude experiments on pig eyes has now evolved to more than 10,000 high-precision, compact, tabletop lasers deployed worldwide at eye clinics and LASIK centers. In the LASIK procedure, excimer laser pulses at 193 nm are used…
