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 Qswitching. We investigate the effectiveness of different Q-switch configurations and analyze the Q-switch opening time of each configuration.
