In addition, the temporal variation of ASE maxima in the presence of the signal pulse is investigated and amplification of the squared signal pulse with duration of 10ns and the power of 0.3-watt is simulated. }, URL = {http://opsi.ir/article-1-1447-en.html}, eprint = {http://opsi.ir/article-1-1447-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2018} }
