    300W High Power Fiber .jpg

    Main Advantages:
    1.Output power up to 320 W
    2.Wavelengths: 915nm and 976 nm
    3.Stabilized spectrum over temp and current
    4.Fiber core 200 μm,NA 0.22

    5.1064nm laser protect

     

     


    The product uses advanced fiber coupling technology to realize 320W high-power in a fiber with numerical aperture NA0.22 and 200um fiber core, and 95% of the power transmitted in the range of NA0.18, so that the laser power is more concentrated and higher brightness. At present, the module can provide output wavelength of 915nm and 976nm  its spectral width FWHM is < 4.5nm, which enables customers to have higher stability when selecting laser applications with different wavelengths. The module has a 1064nm laser isolation mechanism, which is ideally suited for pumping applications such as industrial fiber lasers and fiber laser amplifier and direct diode material processing systems. It avoids damage to the laser module caused by the reverse transmitted light in the system and improves the safety and stability of the whole system.
