Good day,

There are a lot of parameters to take into account when designing a cladding power stripper. Can you be a bit more specific about your system? For instance, how much input pump power do you have? Is the 80 total input power or is it the amount you need to strip? Also, do you have an estimate of the angular power distribution at the entrance of your CPS (i.e. NA at 13.5% and 5%)? Finally, where do you measure the temperature of your CPS? Is there any way to estimate the fiber temperature from this measurement?

For starters, you can have a look at the attached papers.

BR,

Benoit
