976nm 10W Fiber Coupled Laser Diode Module | Multimode CW
976nm 10W Multimode Continuous Wave Fiber Coupled Laser Module
This high-performance 976nm fiber coupled laser diode module delivers 10W of continuous wave (CW) output power through a precision-coupled multimode optical fiber. Engineered using professional micro-optical coupling technology, this module gathers light emitted by the semiconductor chip and channels it through a small-core-diameter fiber with exceptional efficiency, stability, and long service life — making it an ideal pump source for fiber amplifiers, solid-state lasers, and scientific research applications.
Every unit undergoes rigorous process inspection and aging testing to ensure reliable, consistent performance across its entire lifespan. The integrated anti-reflection (AR) function effectively isolates back-reflected light in the ~1µm wavelength band, providing robust pump protection and safeguarding the laser chip from feedback-induced damage.
Made in Mainland China.

Frequently Asked Questions
Q: What is the center wavelength and why is 976nm significant for fiber laser pumping?
A: The center wavelength of this module is 976 nm. This wavelength corresponds to a strong absorption peak of ytterbium (Yb³⁺) ions and is also highly effective for pumping erbium-doped fiber amplifiers (EDFAs). Pumping at 976nm offers high absorption efficiency, resulting in lower threshold power and higher slope efficiency in fiber laser and amplifier systems compared to other pump wavelengths.
Q: What fiber connector or output interface does this module use?
A: The module outputs through a 105 µm core diameter multimode fiber with a numerical aperture of 0.22 N.A. Please contact us or refer to the product datasheet to confirm the specific fiber connector type (e.g. SMA905, FC/PC) included with your unit, as configurations may vary.
Q: Does this laser module include built-in protection against back-reflected light?
A: Yes. This 976nm fiber coupled module features an integrated anti-reflection (AR) function that effectively isolates reflected light in the ~1 µm wavelength band. This protects the pump laser chip from damage caused by optical feedback, which is especially important in high-power fiber amplifier and laser applications.
Q: What driver or power supply is needed to operate this module?
A: The module is designed to operate from an AC power source via a compatible constant-current laser diode driver. A regulated, low-noise laser driver capable of delivering the required drive current for 10W output is recommended. Consult the full datasheet for specific drive current and voltage parameters before powering up.
