Abstract
A fiber laser amplifier system including a first dual-clad delivery fiber receiving a signal beam and a pump beam, a doped amplifying fiber coupled to the first delivery fiber and receiving the signal beam and the pump beam, and amplifying the signal beam using the pump beam, and a second dual-clad delivery fiber coupled to the amplifying fiber and receiving the amplified signal beam and the pump beam. The system also includes an endcap having an input facet and an output facet. The input facet is coupled to the second delivery fiber and receives the amplified signal beam and the pump beam, and the output facet is configured to pass the amplified signal beam and reflect the pump beam back onto the second delivery fiber to be directed back to the doped amplifying fiber.
