LIEKKI™ YB600-20/125

Product catalog summary

Overview: The document provides technical specifications and performance data for nLIGHT Corporation's LIEKKITM Yb600-20/125DC fibers, which are high-power semiconductor laser amplifier fibers with a large core to cladding area ratio and high photodarkening resistivity.

Specifications:

Optical: Peak cladding absorption at 976 nm is nominally 14.6 dB/m. Cladding absorption at 920 nm is 3.4 ± 0.7 dB/m. The core numerical aperture is 0.08 ± 0.01.
Geometrical and Mechanical: Core diameter is 20 ± 2 µm with a core concentricity error of less than 1.5 µm. Cladding diameter is 125 ± 2 µm with an octagonal geometry. Coating diameter is 245 ± 15 µm, made of low index acrylate. Cladding numerical aperture is greater than 0.46. Proof test exceeds 100 kpsi.

Features:

High peak power and moderate average power amplifiers.
High photodarkening resistivity.
Large core to cladding area ratio and short application length.
Matching 6+1:1 pump to signal combiner available.

Applications: The fibers are suitable for high-power amplifiers and marking applications.

Performance Data: The document includes a graph showing signal power versus absorbed pump power at 920 nm, indicating an efficiency of 74%.

Notice: nLIGHT Corporation reserves the right to make changes to specifications and product descriptions without notice and offers a limited warranty for customer satisfaction.
