2024
Recently, the Vico Cup·OFweek 2024 Laser Industry Annual Awards Ceremony was held in Shenzhen. After multiple rounds of evaluation by an expert jury, industry user online voting, and senior industry editors, Changguang Huaxin stood out from nearly a hundred participating projects. 650W 220μm 976nm Wavelength-Locked Lightweight Fiber-Coupled Module Awarded the Best Semiconductor Laser Technology Innovation Award!
High-performance fiber lasers impose higher requirements on the specifications and reliability of pump source modules. Therefore, developing fiber-coupled modules with high electro-optical efficiency, low temperature drift, wavelength locking, lightweight design, strong environmental adaptability, and efficient heat dissipation is the mainstream demand in the research market.
Based on independently developed high-brightness, high-efficiency single-bar chips, Changguang Huaxin utilizes external cavity feedback wavelength locking, high-reliability optical packaging, high-precision beam shaping, high-density beam combining, and high-efficiency fiber coupling technologies, combined with a self-developed fully automatic production line for research fiber-coupled modules Active Alignment, to develop the 650W 220μm 976nm wavelength-locked lightweight fiber-coupled module.
