I have a 6m YDFL fiber in my hand and looking to build a ring fiber laser cavity that could have the highest gain so that I can easily achieve Q-switch or modelock with my current SA.
However, the YDFL I have is not Liekki and the spec is incomplete as shown below. Is there anyway to identify a suitable length for my YDFL based on the current spec?
Technical Specs
Brand: Newport
Fiber Type: Ytterbium Doped
Mode Field Diameter, Nominal: 5.1 - 6.3 @1085 nm µm
Cladding Diameter: 125 ±1 µm
Coating Diameter: 245 ±15 µm
Cable Diameter: 2.5 mm
Operating Wavelength: 1030 - 1100 nm
Cut-off Wavelength: 800 - 900 nm
Buffer Coating Material: Dual Acrylate
Maximum Attenuation: ≤50 @1200 nm dB/km
Numerical Aperture: 0.14 - 0.16
Proof Test: 100 kpsi
Absorption at Pump/Peak: 1700 (nominal) @977 nm dB/m
Thank you in advance for those who answer
we have been able to successfully demonstrate switchable dual wavelength and tunable output wavelengths of mode-locked Yb-doped fiber laser by incorporating SMF–FMF–SMF combination as a SA in the ring cavity.
