Lasers Power Improved Materials Processing

Hank Hogan, Contributing Editor, [email protected]

For lasers, materials can present a manufacturing challenge. Polymers may be best processed with light of a particular wavelength, while metals may respond best to a specific power density. No matter the material, manufacturing fine features can often be improved with the use of sufficiently short pulses. A look at several examples shows how lasers are enabling advanced materials processing, although challenges remain. Lasers can drill precise holes if the light arrives in ultrafast pulses. The dividing line between ultrafast and other pulses has to do with how long it takes heat to move...Read full article
