Patent issued for fiber laser system with improved output power

Mountain View, Calif. – Mobius Photonics, a producer of short pulsed fiber laser sources (IR, green, and UV laser) that are used in laser microprocessing applications, has been granted US patent number 8,009,705, for "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, reducing 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.

Mobius Photonics Inc. 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 super-resolution microscopy.
