| 摘 要： | 提出了一种基于相移光栅(PSG)的多波长掺铒光纤激光器的结构。在该结构中,使用双相移点相移光栅作为波长选择器件,该光栅是在普通布拉格光栅上插入两个相移点而形成的。以980nm的激光二极管(LD)作为抽运源,通过调整偏振控制器(PC),在室温下得到了稳定的三波长激光输出。通过连续25min的观察,观测到输出波长的峰值波动范围小于0.6dB。研究了相移光栅激光器的温度特性,通过设置不同的温度(25℃～85℃),实现了此类基于相移光栅激光器的微调谐。该掺铒光纤激光器可同时输出多个稳定的波长,因此可应用于多波长干涉测量以及全光通信等领域中。 |

| Abstract: | A multi-wavelength fiber laser with phased-shifted fiber grating (PSG) is proposed. The phase-shifted fiber grating with two phase shift points is used as the wavelength selection device which is formed by inserting two phase shift points in the Bragg grating. Under 980 nm laser diode (LD) pumped, stable triple-wavelength can be obtained by adjusting the polarization controller (PC) at the room temperature. The triple-wavelength output power fluctuation is less than 0.6 dB within 25 min. Further more, the temperature tunability of the wavelength of the fiber laser is investigated. The output wavelength can be tuned with the temperature changing from 25 ℃ to 85 ℃. Due to the stable multiwavelength output, the fiber laser can be used in the multiwavelength interference measurement and optical communication systems. |
