Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 50w 976nm ws fiber coupled diode 1nm fwhm. Operating a state-of-the-art factory, we specialize in the entire production spectrum—from high-performance chips, TO/F/C Mounts, COS, and MCC bars, to robust stacks and advanced fiber-coupled solutions.
50W 976nm Wavelength Stabilized Fiber Coupled Diode
Features:
- 976nm wavelength (stabilized ±1nm), 50W stable CW output
- 105μm+SMA905 standard-compatible optical transmission
- 1m/0.9mm jacket for flexible industrial deployment
- ultra-narrow linewidth (FWHM<1nm)
Applications:
- Laser Pumping: Dedicated pump source for Nd:YAG/Yb-doped solid-state lasers and fiber lasers
- Material Processing: Precision marking, thin film cutting, and plastic welding
- Medical Aesthetics: Dermatological treatments (pigmented lesion removal, hair removal) via laser system integration
- Industrial Sensing: Pumping for optical parametric oscillators (OPO) and laser-based detection systems

976nm 50W fiber-coupled diode laser stands out with its ultra-narrow linewidth (FWHM<1nm) and high wavelength stability (±1nm). Equipped with 105μm SMA905 fiber (1m/0.9mm jacket) and delivering reliable high-power output, it is an ideal high-performance pump source for Nd:YAG/Yb-doped solid-state/fiber lasers, and perfectly suited for precision material processing, advanced industrial sensing and other scenarios requiring stringent wavelength control.
