Large mode area double-clad EDFA

High power erbium amplifier

Based on innovative technology of Yb-free Double-Clad Er-doped Fibers, the FOA-EDFA-HP-30-1 series offers unprecedentedly high level of nonlinearity threshold (typical parameters of gain fiber: MFD~25µm, length ~6 m).
 
With the demonstrated pulse energy of > 1mJ in 100ns pulse and > 600 nJ in sub-ps pulse, the FOA-EDFA-HP-30-1 makes 1.5 micron laser sources competitive with Yb-doped fiber lasers in terms of peak power.
 
In the standard configuration and with 50W pump power @ 976nm, the FOA-EDFA-HP-30-1 allows one to extract more than 5-W average power in the range of 1550-1600 nm with diffraction limited beam quality. Higher output power and efficiency up to 40% are available upon the request.
