Abstract
A fiber laser system includes a high power pump laser, an optical fiber that is aligned to receive output from the high power pump laser. The fiber laser system includes a first pair of orthogonally opposed, periodic electrode structures longitudinally aligned on opposite first and second sides of the optical fiber. The fiber laser system includes a controller that is communicatively coupled to the first pair of periodic electrode structures. The controller performs variable period poling of the first pair of periodic electrode structures to achieve quasi-phase matching (QPM).

A fiber laser system comprising:
- a high power pump laser;
- an optical fiber that is aligned to receive output from the high power pump laser;
- a first pair of orthogonally opposed, periodic electrode structures aligned on opposite first and second sides of the optical fiber;
- and
- a controller communicatively coupled to the first pair of periodic electrode structures and that performs dynamically adjustable period poling of the first pair of periodic electrode structures to achieve quasi-phase matching (QPM) with wavelength agility.
