Hi all !
There is a question I can't find an appropriate answer.
Conceptually, I can see what is ASE (amplified spontaneous emission) in lasers such as fiber lasers, but..... what information does a measurement of the ASE spectrum give to us ?
I know that reducing the ASE is of great interest to increase the S/N ratio for optical amplifiers, but when studying lasers, what is the need in measuring the ASE spectrum ?
Is it a measurement of the gain spectrum or something like that ?
Thank you
