    • 976nm High Power Fiber-coupled Semiconductor Pump Module     


    Due to the fiber laser pumped at the 976nm, the gain fiber has a higher absorption coefficient for the pump light. Under the same pump power injection, compared with the 915nm pump, the 976nm  pumping scheme is adopted. The output power of the fiber laser It will be 13% higher, and the gain fiber length required for 976nm wave pumping needs is shorter, which directly reduces the material cost, while also effectively reducing the nonlinear effect, the loss of optical efficiency, and the difficulty of thermal management.

    Note:

    1. Wavelength-temperature coefficient refers to the wavelength drift of each degree rise in cooling plate temperature.

    2. The bending radius of the fiber should be greater than 300 times of the fiber cladding diameter.

    3. Exceeding the normal conditions range will shorten the service life.
