Eye Safe Wavelength Optical Fibers

With the advent of doping technologies allowing the 2-Photon pumping effect for high efficiency energy conversion the intrinsic safety of longer wavelength lasers has become a reality.

Optical efficiencies of over 60% for Tm (λ 2μm) now approach that of Yb (λ 1μm) opening safer, more user friendly industrial and aerospace markets.

Optical Benefits

  • High peak powers with reduced susceptibility to Stimulated Brillouin Scattering (SBS) & other non-linear effects
  • λ1550nm  -  λ 2150nm operating wavelengths

Optical Benefits

  • Tm doped fibers using the 2-Photon effect achieve quantum efficiencies of > 60% when pumped at λ 793nm
  • Er-Yb doped fibers achieve quantum efficiencies of > 35% when pumped at λ 976nm

Mechanical Benefits

  • All Nufern EyeSafe laser and amplifier fibers are made with silica doped cores and synthetic quartz cladding yielding maximum strength and fatigue failure resistance.

Mechanical Benefits

  • All EyeSafe fibers offer telecom life expectancies and use GR-20 rated materials and processes for long life in application.
