Pulsed fibre laser with spatial and temporal control

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.
