All-fiber periodically Q-switched laser

Appl Opt. 2010 Aug 20;49(24):4520-3. doi: 10.1364/AO.49.004520.

Abstract

A short linear cavity erbium fiber laser is adapted to become a Q-switched laser by using a new and simple loss switching technique. The technique utilizes the inherent flexibility of optical fiber to rapidly drive the fiber end in and out of alignment with a cavity mirror, creating the conditions necessary for Q-switching. We investigate the effectiveness of different Q-switch configurations and analyze the Q-switch opening time of each configuration.
