Lasers for Micromachining: Shorter Pulses, More Power Jun 5, 2018 — Smaller devices, tighter tolerances, and higher performance demand finer and finer features — hence the increasing need for micromachining. For lasers, this often translates into a requirement for shorter pulse widths. However, these must be at the right wavelength. What’s more, the entire solution, including the laser, must be cost-effective. Hitting that combination can be a challenge, but it’s one that micromachining specialist Potomac Photonics of Baltimore addresses by having an array of...
