  • In the rapidly evolving fields of industrial laser systems, optical sensing, and cutting-edge scientific research, the demand for high-performance, reliable, and efficient laser sources has never been greater. At the forefront of this technological wave are 974nm and 976nm butterfly packaged fiber-coupled diode lasers, available in power grades of 300mW, 400mW, 500mW, and 600mW. These specialized modules are not just components; they are the critical enablers powering the next generation of applications, from high-efficiency fiber laser pumping to precision gas sensing and beyond. As industry leaders seek to optimize performance, reduce costs, and enhance system stability, our advanced 974/976nm butterfly laser modules have emerged as the definitive solution, setting new benchmarks for quality and versatility in the global photonics market.

The Unmatched Advantages of 974nm & 976nm Wavelengths

The selection of 974nm and 976nm is far from arbitrary; it is rooted in profound material science and application-specific advantages.

01.Superior Pumping Efficiency

The 974/976nm spectral range aligns perfectly with the dominant absorption peak of ytterbium (Yb) and erbium (Er) doped gain media, a cornerstone of modern fiber lasers and amplifiers. Compared to the traditional 915nm pump sources, our 976nm lasers boast an exceptional optical-to-optical conversion efficiency of up to 85%, a significant 10% improvement. This high absorption coefficient translates to more effective energy transfer, lower thermal load, and a dramatic reduction in required pump power, directly lowering operational costs and extending the lifespan of the entire laser system.

02.Precision Wavelength Stability

Featuring integrated Fiber Bragg Grating (FBG) stabilization, our lasers deliver an ultra-narrow linewidth (<1nm) and exceptional wavelength accuracy (±1nm). This precision is indispensable for applications demanding spectral purity, such as TDLAS (Tunable Diode Laser Absorption Spectroscopy) gas sensing, where even minor wavelength drift can result in catastrophic measurement errors.

03.Robust Butterfly Packaging

Encased in a hermetically sealed 14-pin butterfly (BF14) package, these modules integrate a high-precision Thermoelectric Cooler (TEC) and a precision thermistor. This advanced thermal management system ensures unparalleled wavelength and power stability across a wide operating temperature range (0°C to 70°C), guaranteeing consistent performance in challenging industrial environments. The robust, hermetic design also provides excellent resistance to vibration, humidity, and mechanical shock, ensuring a Mean Time To Failure (MTTF) of over 10,000 hours.

04.Flexible Fiber-Coupled Output

Each module comes standard with a pigtailed single-mode (SM) or polarization-maintaining (PM) fiber, culminating in an FC/APC or SC/APC connector. This plug-and-play design facilitates seamless integration into existing systems, enables flexible optical path design, and allows for efficient, remote light delivery-eliminating the complexities of free-space alignment.
