High-order cladding modes
Did you know?
WebFor high-power fiber lasers and amplifiers, there are special cladding mode strippers which can remove cladding light at high power levels. Due to their different propagation constants, core modes and cladding modes usually do not exhibit any noticeable coupling with each other. This means, e.g., that light launched into the core will remain ...
