Abstract
Official abstract text for this publication.
A high-power optical fiber laser includes: an oscillator ( 1 ); a pumping laser ( 5 ) able to emit a high-power pumping optical radiation beam; and a signal-amplifying optical fiber ( 3 ) able to receive the optical source signal and the high-power pumping optical radiation beam so as to generate a high-power laser beam. The pumping laser includes a plurality of pumping multimode laser diodes ( 7 a - 7 f ) and a laser cavity, the laser cavity including a double-clad fiber ( 4 ) including: a neodymium-doped monomode waveguide; a fiber Bragg grating ( 9 ) forming one end of the laser cavity; and a fiber reflector ( 11 ) forming the other end of the laser cavity, the monomodefiber laser being able to generate a laser radiation beam when it is optically pumped by a pumping radiation beam originating from the plurality of pumping laser diodes in order for the laser cavity to emit a high-power pumping laser radiation beam.
First claim
