LIEKKI Yb1200-20/125

nLIGHT

LIEKKIYb1200-20/125 fibers are very highly doped fibers with low photodarkening loss ideally suited for compact, medium average power pulsed amplifier applications where large mode area and short fiber length are critical for suppression of nonlinear effects. The high-efficiency, low-NA core provides high beam quality.LIEKKIYb1200-20/125 fibers are available as double-clad (Yb1200-20/125DC) and double-clad polarization maintaining (Yb1200-20/125DC-PM) fibers.Features:Industry leading fiber deposition process ? Direct Nanoparticle DepositionLarge, low-NA core for low nonlinearity and high beam quality applicationsVery high pump absorption enabling less than 2 m application lengthsLow photodarkening lossProof tested to > 100 kpsi for long-term mechanical reliabilityAcrylate coating enables fiber applications in extreme environmental conditions: Proven to operate up to 120?C and in extreme humidity.Matching passive fibers available with optimized design for minimal splice lossApplications:Medium average power pulsed fiber amplifiersMarking and material processing lasersIR source for frequency doubling
