PRESS RELEASE

G1R3 pulsed fibre laser

Mobius Photonics has introduced its the G1R3, a fibre-based, short-pulse, and high-repetition-rate laser system that can generate ultraviolet, green, or infrared output. The laser is intended for precision materials processing applications such as micromachining, solar cell manufacture and via drilling. It has been designed to quickly and efficiently ablate material while minimising the heat affected zone produced.

The G1R3 is based on a master-oscillator, fibre-power-amplifier (MOFPA) architecture. The standard system is available in three configurations: one that produces up to 30W of 1,064nm output, a second that produces up to 18W at 532nm, and a third that produces up to 12W at 355nm. Mobius has also demonstrated power scaling of its G1 platform to reach higher average powers in the UV and green. In addition, the company holds a patent covering multi-head operation from a single system. Using this technique, synchronised laser heads could provide higher system power output, or, if used separately, could allow parallel material processing.

G1R3 systems provide tunable pulses 2-6ns in duration, with repetition rates as high as 2MHz. Pulse widths remain consistent with changes in repetition rate, and the G1R3 laser produces diffraction-limited output over the range.
