ABSTRACT:
Single transverse mode fiber amplifier and laser operation is obtained with a multi-mode signal core surrounded by cladding containing irregular microstructuring that causes loss in all of the core modes except the fundamental while maintaining robust guiding of the fundamental mode resulting in higher fiber laser power capacity.
