Al-glass kW fibre laser end-pumped by MCCP-cooled diode stacks

High power industrial fibre lasers are typically pumped by single emitter diodes, with pump power aggregation and the fibre laser cavity being achieved in a monolithic "all-fibre" architecture comprising fused fiber bundles, fiber Bragg grating reflectors and numerous splices. We adopted a...

Zusammenfassung:High power industrial fibre lasers are typically pumped by single emitter diodes, with pump power aggregation and the fibre laser cavity being achieved in a monolithic "all-fibre" architecture comprising fused fiber bundles, fiber Bragg grating reflectors and numerous splices. We adopted a very different approach based on end pumping of a stable multimode oscillator utilizing free space optics.
