Fiber laser amplifier residual pump power?

Very roughly, how we can estimate the residual pump power (976nm, 200W) for 1064 nm signal? The 1064 nm signal beam is initially input with 100 mW. The fiber amplifier is based on Yb-doped double...

What is the physical reason that SHG beam has asymmertic shape oafter BBO crystal? How to make good quality of SHG beam shape?

Hi, I am doing experiments to make SHG beam from an ultrashort pulse laser. I use BBO crystal and lens to focus the beam into the crystal. I found that the output beam is a very asymmetric (looks...
