For fiber laser between 890 – 1100 nm

iXblue offers a complete range of Neodymium fibers with some unique properties.

iXblue Neodymium Aluminosilicate double clad fibers have been developed to maximize fiber efficiency through a precisely controlled host composition. Compared to a standard Neodymium fiber, the 1.06-micron emission is reduced through careful fiber design optimization.

Our double clad fibers are routinely tested to various parameters such as photodarkening and environmental behavior.

Single clad fibers are also proposed and would be ideal to build seeder sources.



Benefits & Features

  • Host composition optimized for high energy efficiency and low clustering
  • Low splicing losses
  • High NA, High performance low-index cladding
  • Low background losses
  • Low macrobending losses at operating wavelength


  • 0.9 to 1.064 µm fiber lasers
  • Seeder source at 10xx nm

    Optics Express, Vol 26, No. 8 – APRIL 2018

    We present the first frequency-doubled neodymium-doped fiber laser generating multi-watt CW power near 450 nm. A bow-tie resonator incorporating a LBO nonlinear crystal is integrated within a Nd-doped fiber laser emitting near 900 nm. This scheme achieves an IR to blue conversion efficiency close to 55% without any active control of the internal resonant cavity…
