Hi
Here they explain the concept of gain clamping in steady state lasers: http://books.google.com/books?id=x5...DYQ6AEwAzge#v=onepage&q=gain clamping&f=false. They say:
"The decrease in gain stops once the gain in the medium γ(v) exactly balances out the cavity losses α resulting from parasitic lasing and mirror losses."
However they never say why the gain stops decreasing at that point, and I haven't been able to find the explanation in any book so far. I know that gain = losses in CW-lasers -- otherwise they wouldn't be CW, but that doesn't explain why we have an equality. Does anybody know the reason?Niles.
