Abstract
A laser amplifier includes a pump source and an optically active fiber having an input portion configured to receive a signal source and an output portion. The pump source is optically coupled to the optically active fiber. The laser amplifier also includes an output fiber optically coupled to the output portion of the optically active fiber. The output fiber includes a rare-earth element. The laser amplifier further includes a beam expansion section joined to the output fiber.
Claims9
A laser amplifier comprising:
- a pump source;
- an optically active fiber having an input portion configured to receive a signal source and an output portion, the pump source being optically coupled to the optically active fiber;
- a doped output fiber optically coupled to the output portion of the optically active fiber, wherein the doped output fiber comprises a rare-earth element;
- and
- a beam expansion section joined to the doped output fiber, wherein the beam expansion section is characterized by a uniform index of refraction as a function of position.
