摘要：
There is provided a wide-band optical amplifying device capable of performing amplification over a wideband in infrared range. The wideband optical amplifier is characterized in that optical amplification is realized by optically exciting a glass or a crystal having bismuth as fluorescent center and that the amplification wavelength is 1000 nm to 1600 nm.
