Brief
This article proposes and demonstrates a highly integrated array of cladding mode strippers for fiber lasers, which reduces space and weight by bundling multiple CMSs into a single device while managing heat effectively.
Summary
This article proposes a design to integrate multiple cladding mode strippers (CMSs) into a single device for compact high-power fiber lasers. By staggering the hottest light-stripping regions, the integrated CMS array can operate at full power without significant heat accumulation or cross-influence, achieving a 50% to 66% reduction in space and weight for two- and three-CMS arrays, respectively. This miniaturization of a bulky and hot component contributes to higher power-to-volume ratios in industrial fiber lasers.
