HIGH-POWER COMPACT FIBER LASER

摘要

A fiber laser comprises a wound fiber (10) having a core and a cladding. The fiber is pumped by an energy source to produce a high-quality laser beam. The fiber is wound in a flat wound formation (12) such that both ends (16, 18) of the fiber are disposed toward the outside of the formation. The wound fiber is optically pumped by a pumping source (60) located along an edge of the wound formation. In one embodiment, the fiber is pumped by a close coupled laser diode bar and the fiber comprises a rare earth doped core surrounded by a cladding material.
