Optical Fibers
Optical Fibers
Delivering light for continuous wave and pulsed fiber lasers.
Absorptive, powerful, reliable.
We offer active and passive optical fibers (produced in Finland) for CW, quasi-CW and short-pulsed fiber laser and amplifier applications extending from the low to the high power regime. LIEKKI® active optical fibers are fabricated using our proprietary direct nano-particle deposition process resulting in high performance and high reliability. Active fibers are available with either Ytterbium (Yb) or Erbium (Er) and offered over a range of dopant concentration levels, cladding types and core diameters.
Industry-leading optical fiber
Proven Reliability
Unmatched reliability proven over the years with thousands of high power lasers deployed across a variety of industries and applications.
Independent Core Profile Control
nLIGHT Liekki fiber provides precise profile and doping control with hundreds of layers of nanoparticles.
Direct Nanoparticle Deposition Process
realNA
nLIGHT’s proprietary single-step deposition process reduces background loss and application length to provide higher efficiency.
The most accurate fiber core NA measurements coupled with excellent homogeneity and batch-to-batch uniformity provide consistent performance.
