Raman amplification of 1.50-μm laser diode light in a low fiber loss region
Abstract
Raman amplification utilizing the second Stokes line of 1.32-micron Nd:YAG laser light in a single-mode silica fiber was observed. Raman gains of 24 dB have been obtained for 1.50-micron laser diode light in the low-loss region. In addition, the signal-to-noise (S/N) characteristics of Raman amplification using the second Stokes line was investigated. As a result, it became clear that the S/N ratio was inferior to that in the 1st Stokes line by about one order of magnitude.
