2.2  kW single-mode narrow-linewidth laser delivery through a hollow-core fiber

Optica, 2023
Antiresonant hollow-core fibers (AR-HCFs) have opened up exciting possibilities for high-energy and high-power laser delivery because of their exceptionally low nonlinearities and high damage thresholds. While these fiber designs offer great potential
