The stress on either the erbium-doped or the normal optical fiber inside a cavity can cause output modulation, wavelength tuning in the gain band, and selection of the transition at 1.53 or 1.56 microm in an erbium-doped optical fiber laser. These phenomena are explained with the birefringence of the optical fiber under stress, the polarization properties of the directional coupler loop, and the condition of the laser oscillation. These phenomena may have some practical use in output power control, wavelength tuning, and sensors.
腔内掺铒光纤或普通光纤上的应力会导致输出调制、增益带内的波长调谐,以及掺铒光纤激光器中1.53或1.56微米处跃迁的选择。利用应力作用下光纤的双折射、定向耦合器环的偏振特性以及激光振荡条件对这些现象进行了解释。这些现象在输出功率控制、波长调谐和传感器方面可能具有一些实际用途。
