The BLD-F976-350-135-22N0 is a high-power, fiber-coupled diode laser module developed by BOX Optronics, delivering up to 350W of continuous wave (CW) output at a central wavelength of 976nm. Designed for industrial and scientific applications, this laser combines high brightness, reliability, and efficient thermal management in a compact and robust package.

The laser features a 135µm core diameter multimode fiber with a 0.22 numerical aperture, ensuring stable beam delivery and compatibility with a wide range of optical systems. With a spectral width of less than 6nm and a wavelength temperature coefficient of 0.3nm/°C, the device offers consistent performance across varying thermal conditions. The module operates with a typical threshold current of 1.0A and reaches full output at approximately 19A, with an operating voltage around 35.5V. Its power conversion efficiency is up to 50%, making it suitable for energy-sensitive applications.

This diode laser is ideal for use in medical systems, material processing, printing, and as a pump source for solid-state or fiber lasers. The module is supplied with a 1.5-meter fiber, optional SMA905 connector, and a protective loose tube for enhanced durability.

Thermal management is critical for stable operation, and the laser is designed for integration with an external heatsink. The device must be operated in a clean or dust-protected environment, and proper ESD precautions are essential during handling. With its high output power and fiber-delivered beam, the BLD-F976-350-135-22N0 offers a reliable solution for demanding photonic applications where precision, power, and stability are essential.
