In-Fiber Acousto-Optic Devices for Laser Applications

These authors review in-fiber acousto-optic devices that have demonstrated new possibilities for the control of Q-switched distributed feedback and mode-locked all-fiber lasers—in other words, tools for using sound to control light.

All-fiber lasers provide certain benefits compared to other laser systems. First of all, since optical fibers are flexible, they can be confined to a tight space, making it possible to construct very compact devices. Another advantage is that laser light is restricted to the core of the fiber, providing a well-controlled beam shape and superior pointing stability. Thermal management is easier as well, because an optical fiber has much more surface area per unit volume than a bulk laser crystal.
