2025

The 5th Laser Golden Glory Awards Ceremony 2025 was held in Shanghai, Changguang Huaxin's 976nm 1400W 300μm Tail Fiber Pump Module won the "2025 Laser Golden Glory Award" for New Product.

Due to its high absorption and technical advantages, the 976nm pump source has become the mainstream pumping solution in the industrial fiber laser field in recent years. With the intensifying competition in the industrial fiber laser market, the demand for cost reduction is increasing day by day. Pump sources are rapidly developing and iterating towards higher power and higher operating current, facing challenges in thermal management and high junction temperature operation.

Changguang Huaxin, in response to market demand, developed high junction temperature and high reliability laser chips, and based on its own chip and pump packaging advantages, developed the 976nm 1400W 300μm tail fiber pump module, effectively solving the difficulties of pump source thermal management and high junction temperature operation. It can be directly applied to handheld welding pumps, industrial fiber laser pumps, etc., featuring high reliability and outstanding high junction temperature operation.

Changguang Huaxin: IDM Semiconductor Laser Manufacturer

Changguang Huaxin is dedicated to the research and production of semiconductor laser chips. Its core technology covers the most critical areas of the semiconductor laser industry, overcoming long-standing technical challenges such as epitaxial growth, cavity surface treatment, packaging, and fiber coupling. It has established a fully independent and controllable complete process platform and mass production line from chip design, MOCVD (epitaxy), FAB wafer fabrication, cleaving/coating, packaging, testing, optical coupling, to direct semiconductor lasers. It owns three major production lines of 2-inch, 3-inch, and 6-inch wafers, with two main product structures: edge-emitting EEL and surface-emitting VCSEL. It covers five major material systems: GaAs (Gallium Arsenide), InP (Indium Phosphide), GaN (Gallium Nitride), SiC (Silicon Carbide), and SiPho (Silicon Photonics). It is one of the few IDM semiconductor laser companies globally with key process production capabilities such as 6-inch line epitaxy and wafer manufacturing, strongly promoting the rapid development of China's ultra-high power laser technology and its applications.
