In February, Changguang Huaxin announced for the first time a single-chip with power exceeding 100W. This research achievement was officially published in the internationally renowned SCI journal "Photonics." The double-junction single-chip diode laser has a continuous power at room temperature exceeding 132W (about twice the maximum power of single-chip lasers reported in literature), representing the highest power level reported for single-chip lasers to date, continuously leading the technological development in the high-power chip industry. The article is titled "Double-Junction Cascaded GaAs-Based Broad-Area Diode Lasers with 132W Contin

Professor Wang Jun's research team from Changguang Huaxin CTO and Sichuan University recently published their latest research results in Light: Science & Applications, systematically studying the advantages of multi-junction VCSELs in electro-optical conversion efficiency through a combination of theoretical simulation and experiments. Simulations indicate that a 20-junction VCSEL can achieve over 88% efficiency at room temperature. Experimentally, a 15-junction VCSEL achieved a maximum efficiency of 74% at room temperature, with a corresponding differential quantum efficiency exceeding 1100%, representing the highest electro-optical conversion efficiency and differential quantum efficiency reported for VCSELs to date.

As the core component of lasers, high-power semiconductor single-bar chips directly affect the size and cost of laser systems. After years of iteration, commercial chip power reached 50W in 2023. Higher power remains the industry's focus, representing the development level of comprehensive chip technology. The highest known level recently achieved a breakthrough in structural design and manufacturing technology with the ultra-high-power single-bar chip from Changguang Huaxin. The developed single-bar chip has a continuous power exceeding 100W at room temperature (chip stripe width 500μm) and an efficiency of 62%, making it the highest power single-bar chip reported to date.
