We report the design and performance of medium slope efficiency (64%) Holmium-doped fiber amplifiers (HDFAs) with novel alternative in-band pump wavelengths in the 1720-2000 nm spectral region. We …
We report the design and performance of a packaged broadband PM hybrid HDFA/TDFA in the 2000–2100 nm band using all-single-clad doped fibers. Internalsmall signal G = 49.1 dB, small signal NF = 6…
We report the broadband spectral performance of a three-stage, high gain, single mode, high output power (25 W) polarization-maintaining (PM) hybrid Ho-doped and Tm-doped fiber amplifier at signal …
