Abstract

Optical gain characteristics of an Er³⁺ -doped silica fiber have been studied by end pumping with a 1.48 μm InGaAsP high-power laser diode. A gain as high as 12.5 dB was obtained for an absorbed pump power of 16 mW with a 3-m-long fiber. By constructing an Er³⁺ fiber ring cavity with a 3 dB single-mode fiber coupler, we have obtained continuous wave laser oscillation at a wavelength of 1.553 μm.
