Abstract
The present invention provides an apparatus for generating L-band light source and an optical signal amplifier, specifically, relates to an apparatus for generating L-band light source by increasing amplification gain against an L-band light to execute a stable resonating operation, and to an optical amplifier which amplifies L-band light signal efficiently. That is, it is possible to use the output light of the first optical fiber amplifier as a pumping light of the second optical fiber amplifier by connecting the first optical fiber amplifier for supplying a maximum amplification gain against an input light having a wavelength of 1530 nm to 1560 nm with the second optical fiber amplifier for supplying a maximum amplification gain against an input light having a wavelength of 1570 nm to 1610 nm in series, thus securing a satisfied amplification gain against a L-band light and to generate a desirable light source.
