Author's Profile
Yonggui He
kW Systems Division | Senior High-Power Laser Engineer
I am a high-power laser engineer with over ten years of experience in industrial laser systems.
My work focuses on kilowatt-class semiconductor and fiber-coupled lasers, with an emphasis on manufacturable design, system integration, and real-world industrial applications.
Engineering & Technical Background
After graduating from Xi’an University of Technology with a degree in Optical Information Science and Technology, I began my career in the field of high-power laser engineering.
A key part of my early professional experience involved technology transfer projects with LIMO (Germany). Through four separate technical training programs in Germany, I gained hands-on experience in advanced laser integration technologies and industrial implementation methods.
Optical beam shaping and homogenization
Optical beam combining technologies
Fiber coupling for high-power laser delivery
Industrial laser module integration
Role at VivLaser
At VivLaser, I serve as Deputy General Manager of the Kilowatt Laser Division, where I am responsible for the development of kilowatt-level fiber-coupled laser products.
My work covers the full product lifecycle, including system architecture planning, core module development, manufacturing coordination, and product iteration based on real application feedback. I work closely with both internal teams and external partners to ensure that engineering decisions align with industrial requirements.
Technical Focus Areas
High-power semiconductor laser systems
Kilowatt-class fiber-coupled lasers
Optical beam shaping and homogenization
Optical beam combining
Fiber coupling and power delivery
Industrial laser product development
Manufacturing validation and reliability testing
Engineering Approach
In my engineering work, optical performance alone is not sufficient. Laser systems must also demonstrate long-term stability, manufacturability, and reliability under real industrial operating conditions.
I focus on balancing performance, process tolerance, and lifecycle cost to ensure that laser products can be consistently produced and deployed in demanding industrial environments.
