2kW Narrow Linewidth Single Mode Fiber Laser
  • The Ideal Fiber Laser For High-Power Spectral Beam Combining

    The average spectral bandwidth (20dBRMS) of the 2kW mass-produced laser model is less than 0.25nm, with a center wavelength deviation of no more than 0.1nm and M2<1.5, which make it meet the requirements for ultra-high power spectral beam combining.

  • Compact, Lightweight, and Modular Design Concept

    The oscillator stage and amplifier stage adopt standalone design, making their maintenance easy. Due to the brand new design, the total weight does not exceed 20 kg, and the more the fiber lasers are used for beam combination, the more significant the weight reduction effect is.

  • Adopting 976 nm Highly Efficient Pumping Technology

    The 976 nm highly efficient pumping technology increases the laser's E-O conversion efficiency to over 40%.

  • High Engineering Reliability

    After mass production and harsh environmental testing,this laser model is found to have good reliability and environmental adaptability.

  • Supporting Subsystem Working Mode

    Multiple fiber lasers can form a laser source subsystem that is compatible with unified control and power supply mode, fully meeting the functional requirements of users for laser sources.
