摘要：The invention relates to a high power amplifier waveguide for amplifying anoptical signal wherein photo darkening due to high optical flux is reduced considerably.This is achieved by providing a cladding pumped amplifier waveguide wherein the opticalmode overlap to the active material of the waveguide is low and/or wherein the activematerial is distributed over a large cross sectional region of the waveguide.
