The G1R3 fiber laser source is a short-pulse, air-cooled system that generates ultraviolet, green, or infrared output.

The G1R3 fiber laser source is a short-pulse, air-cooled system that generates ultraviolet, green, or infrared output. Based on a master-oscillator, fiber-power-amplifier (MOFPA) architecture, system configurations include up to 30 W at 1064 nm output, up to 18 W at 532 nm, and up to 12 W at 355 nm, all of which provide tunable pulses between 2 and 6 ns and allow repetition rates as high as 2 MHz. Applications include micromachining, solar cell manufacturing, and via drilling.

Mobius Photonics Releases Fiber-Based Laser Source for Precision Materials Processing

MOUNTAIN VIEW, Calif., May 11, 2011 – Mobius Photonics, an innovative producer of short pulsed fiber laser sources (IR, green, and UV laser), announces the availability of its “G1R3” laser source. G1R3 is a fiber-based, short-pulse, high-repetition-rate system that can generate ultraviolet, green, or infrared output. It is intended for precision materials processing applications such as micromachining, solar cell manufacturing, and via drilling.

“With the Mobius G1R3 laser design, we’ve parlayed our experience developing fiber-based sources for microelectronic and semiconductor applications into a system that combines short pulses, high repetition rates and high output powers with excellent beam quality,” said Manuel Leonardo, Mobius vice president of technology. “The result is a laser that’s been demonstrated to quickly and efficiently ablate material while producing a minimal heat affected zone. It’s intended for applications that demand precision cutting, scribing or drilling with rapid throughput.”

Mobius’ G1R3 is based on a master-oscillator, fiber-power-amplifier (MOFPA) architecture. The standard system is available in three configurations—one that produces up to 30W of 1064 nm output, a second that produces up to 18W at 532 nm, and a third that produces up to 12W at 355 nm. 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, synchronized laser heads could provide higher system power output, or, if used separately, could allow parallel material processing.

G1R3 systems provide tunable pulses between two and six nanoseconds and allow repetition rates as high as two MHz. Pulse widths remain consistent with changes in rep rate. G1R3 sources produce diffraction-limited output over a range of user-adjustable pulse repetition frequencies and pulse widths. Designed with simple integration in mind, G1R3 lasers are air cooled. A modular product design also facilitates servicing and upgrades.
