FIBER AMPLIFIER WITH INTEGRATED FIBER LASER PUMP

摘要

An optical system adapted to amplify an input signal includes an optical pump supporting the input signal and an optical pump beam The optical pump includes an input port, a first active medium coupled to the input port, and a pump output coupled to the first active medium The optical amplifier includes an amplifier input optically coupled to the pump output and adapted to receive the input signal after passing through the optical pump, a second active medium coupled to the amplifier input, and an amplifier output adapted to output the amplified input signal.
