· Appl. Phys. Lett.; (United States)
Optical gain characteristics of an Er/sup 3+/ -doped silica fiber have been studied by end pumping with a 1.48 ..mu..m 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 Er/sup 3+/ fiber ring cavity with a 3 dB single-mode fiber coupler, we have obtained continuous wave laser oscillation at a wavelength of 1.553 ..mu..m.
