## Abstract We present a single‐pass L‐band erbium doped fiber amplifier (EDFA) based on a large mode area (LMA) fiber. A single transverse mode is maintained through restricted mode launch. Pump light near 974 nm is sent into the core and has high spatial overlap with the signal beam, helping to p
