Picosecond Lasers Transform Volume Manufacturing

Facebook Twitter LinkedIn Email Comments

As picosecond lasers mature, their role in micromachining and a range of other applications expands.

HERMAN CHUI AND JIM BOVATSEK, MKS SPECTRA-PHYSICS

Laser micromachining has revolutionized volume manufacturing, enabling smaller feature sizes, novel device geometries and materials, improved process yields, and reduced production costs. Industries as diverse as consumer electronics, medical devices, clean energy, and automotive have benefitted from nonstop advancements in the technology. One technical challenge of laser micromachining is effectively removing desired material while minimizing the extent of thermal damage, or the heat-affected zone (HAZ), of the remaining material. Ultrashort-pulse lasers deliver intense peak powers that...Read full article
