Title: Cheng Li: Innovator in Optical Fiber Technology

Introduction

Cheng Li is a prominent inventor based in Hubei, China, known for his contributions to optical fiber technology. With a total of 4 patents, he has made significant advancements in methods and devices that enhance laser performance and efficiency.

Latest Patents

One of Cheng Li's latest patents is a method for preventing feedback light of a laser. This innovative method involves fusion-splicing a target fiber to an output fiber of a laser, allowing laser lights generated by the laser to be output from the target fiber. The design ensures that when feedback light is reversely transmitted to the fusion-splicing surface through the target fiber, total reflection occurs due to the refractive index difference. This prevents the feedback light from entering the output fiber and damaging the laser component.

Another notable patent is the optical fiber laser coupler. This device comprises a laser input optical cable, a laser shaping and coupling device, and a multi-beam-mode energy transmission fiber. The multi-beam-mode energy transmission fiber includes a circular fiber core and annular fiber cores, allowing for real-time switching between different beam modes. The adjustable collimating and focusing lens groups enable precise control over the laser beam input into various fiber cores.
