DCF-YB-15/250P-FV：True Phosphosilicate
- The high demand for a photodarkening free
optical fi ber for multi kW single mode
CW fi ber laser applications near 1 µm
has driven the development of this
phosphosilicate fi ber. Manufactured
under a carefully control process, its
refractive index profi le and core chemical
composition allow high reproducibility.
This ensures a reliable batch-tobatch
consistency. With output power up to 1.5 kW
with very low nonlinear effects, this fi ber is
best for industrial applications requiring
high power output.
Features & Benefits:
Photodarkening free excellent batch tobatch
consistency
Accurate matching MFD design with
related passive fiber allows single mode
operation and low splicing losses
High cladding absorption reduces fi ber
length in order to mitigate nonlinear
effects such as SRS
High fi ber laser effi ciency (> 70%)
High stability against pump wavelengths
between 915 nm to 970 nm
Output power up to 1.5 kW
Applications:
High power CW fi ber lasers、Medical
Material processing: cutting and welding
