Pulsed fibre laser with spatial and temporal control
Pulsed fibre laser with spatial and temporal control
We report on novel approach to switch the optical beam profile in a fibre laser using a short piece of special passive fibre. The switching mechanism relies on selective wavelength resonance between the core and a high index surrounding ring in the fibre. Beam switching at 530 kHz from a Gaussian beam shape to a flat-top beam with a ring with corresponding M2 from 1.4 to 3.5 is demonstrated in a modified industrial pulsed fibre laser.

Abstract
We report on novel approach to switch the optical beam profile in a fibre laser using a short piece of special passive fibre. The switching mechanism relies on selective wavelength resonance between the core and a high index surrounding ring in the fibre. Beam switching at 530 kHz from a Gaussian beam shape to a flat-top beam with a ring with corresponding M2 from 1.4 to 3.5 is demonstrated in a modified industrial pulsed fibre laser.
