Title: Walter Fu: Fiber-Laser and Optical Amplification Innovations.

Introduction

Walter Fu is an inventor based in Ithaca, New York, whose patent work includes fiber-laser amplification and optical parametric amplification. He is associated with Cornell University and has 3 patents.

Latest Patents

Fu’s listed patent, “Nonlinear Ultrafast Fiber Amplifiers,” describes a pulsed-laser apparatus that combines pumping light and a seed pulse in a doped fiber-optic cable. As the seed pulse travels through the fiber, nonlinear effects broaden its spectrum. Farther along the fiber, the output pulse shifts toward longer wavelengths and expands in both spectral and temporal domains.

His listed patent, “Fiber Optical Parametric Chirped-Pulse Amplification (FOPCPA),” describes an optical system that stretches pump seed laser pulses, amplifies them in fiber, and combines the resulting pump beam with a signal beam at a different wavelength. A nonlinear interaction in the fiber optical parametric amplifier produces an output signal beam, an idler beam, and an output pump beam.

Career Highlights

Fu’s patent portfolio reflects work on ultrafast fiber amplifiers and fiber-based optical parametric systems. These technologies use nonlinear optical processes to generate and amplify laser pulses.
