Fiber-based MOPA system avoids stimulated Brillouin scattering

Mountain View, CA--Mobius Photonics was granted United States patent 8,009,705 for a "Fiber MOPA System without Stimulated Brillouin Scattering."

Mountain View, CA--Short-pulsed fiber laser (infrared, green, ulraviolet) manufacturer Mobius Photonics was granted United States patent 8,009,705 for a "Fiber MOPA System without Stimulated Brillouin Scattering." The patent covers an optical fiber-based master oscillator power amplifier (MOPA) system that avoids stimulated Brillouin scattering (SBS), a spontaneous phenomenon of light scattering that can occur in an optical fiber and reduce a fiber laser system's optical power.

Mobius' methods for overcoming SBS enable a system that produces high-peak-power, square pulses that are efficiently wavelength converted to desired wavelengths. The invention has particular relevance for applications such as materials processing that demand robust fiber-based systems capable of producing high-quality, high-peak-power, green or UV pulses.

"We are delighted that the United States Patent and Trademark Office has accepted our patent on a fiber MOPA system without SBS," said Kiyomi Monro, Mobius CEO. "Mobius plans to continue to invest in expanding our intellectual property portfolio by leveraging our unique company culture of research and innovation."

Founded in 2005, Mobius Photonics produces fiber-based laser sources for applications ranging from material processing for solar cell manufacturing, semiconductor fabrication and assembly, and flat-panel display manufacturing, to scientific uses such as superresolution microscopy.
