| 中文摘要 | 采用遮挡法引入相移制作了掺Yb相移光纤光栅(PS-FBG)。在制作光栅的过程中,将其作为激光器的谐振腔,通过监测激光器的输出功率来确定相移大小。当激光器的输出功率开始下降时,停止曝光,此时引入的相移为π/2。为了使光栅的特性尽快稳定下来需要对光栅进行退火,这将导致引入的相移小于π/2。为了弥补退火过程中引起的相移降低,需要对退火后的光栅进行二次曝光,以使光栅的相移恢复π/2。利用该方法制作了一只光纤光栅激光器。当抽运功率为100 mW时,获得了25 mW的输出功率,信噪比(SNR)为60 dB。在1 h内; Yb-doped phase-shifted fiber Bragg grating (PS-FBG) has been fabricated with phase shift introduced by shielded method. In the fabrication process, the PS-FBG is used as the laser cavity. Whether the introduced phase-shift is π/2 or not is determined by the laser output power. As long as the output power of the laser begins to drop down, the exposure is stopped, and the phase shift is π/2 then. It is necessary to anneal the PS-FBG to stabilize its characteristics, which will reduce the introduced phase-shift. The second exposure of the PS-FBG is needed to restore the π/2 phase shift. A fiber grating laser has been made with the method. When the pump power is 100 mW, the laser output is 25 mW with signal-noise-ratio (SNR) of 60 dB. Within 1 h the output fluctuation of the laser is less than 1%. The laser is always under single-mode operation when the temperature of the fiber grating is tuned between 25 ℃ and 30 ℃. |
