Laser eases small device manufacturing

A Newport Spectra-Physics product story
Edited by the Engineeringtalk editorial team Mar 17, 2008

Newport's Pantera laser is suitable for applications in solar cell, flat panel display, printed circuit board and semiconductor manufacturing.

Newport Spectra-Physic shas released the picosecond Pantera laser.

This diode-pumped solid-state laser uses a fibre amplifier platform to deliver 12W of stabilised UV power at a wavelength of 355nm.

The Pantera provides picosecond laser pulses at a repetition rate of 80MHz and offers excellent mode quality (TEM00).

Newport's Pantera laser is suitable for applications in solar cell, flat panel display, printed circuit board and semiconductor manufacturing.

"We are very excited to unveil the Pantera laser, the first in a series of laser products that will incorporate our new fibre-based platform", said Michael Kauf, Marketing and Business Development Manager for Newport's fibre Laser Business Group.

"We believe that this laser offers a combination of advantages to enable our customers to manufacture more complex devices with smaller feature sizes, with higher throughput and a lower cost per part".

The Pantera UV laser uses a master oscillator power fibre amplifier (MOPFA) design with a mode-locked seed laser, a powerful fibre amplifier and highly-efficient frequency conversion.

This design provides a combination of high UV power, excellent beam quality and reliability.

The fibre amplifier is powered by fibre coupled, hermetically sealed diodes and is not affected by external influences such as mechanically-induced misalignment, making the Pantera suitable for demanding industrial applications.

Kauf said "The Pantera laser was specifically designed for industrial and OEM customers requiring high precision, high-quality and high throughput material processing".

"The laser's ability to deliver UV wavelength light in picosecond pulses minimises thermal damage to the material and enables higher resolution and higher quality work".

"The high pulse repetition rate ensures smooth processing results even at speeds of multiple metres a second".
