Title: Ming Zhao and a Miniaturized Solid-State Laser Invention.

Introduction

Ming Zhao is an inventor associated with Fuzhou, China, and Ii-Vi Delaware, Inc. His listed patent concerns a compact diode-pumped solid-state laser designed to combine high output power with high beam quality.

Latest Patents

Zhao’s listed patent is “Miniaturized Master Oscillator Power-Amplifier Structure Diode-Pumped Solid-State Laser.” It describes a master oscillator power-amplifier (MOPA) system with a seed-laser oscillator module and a laser-amplifier module. A collimated seed beam enters a gain element, where pump energy is supplied through an end-pump or side-pump arrangement.

The design uses a zigzag path through the gain medium, reflecting the seed beam multiple times to increase amplification and energy extraction. It also describes gain materials with different rare-earth ion concentrations and shapes, along with optical coatings intended to improve pump absorption and guide the seed beam through the medium. The disclosure identifies materials doped with erbium and ytterbium as one possible gain medium and describes potential operation with a 1.55-micron seed source. The patent presents a structure intended to be smaller, simpler, and less costly than prior MOPA laser designs. Zhao is listed with 1 patent.
