| 摘 要： | 对分布布拉格反射(DBR)的透射特性进行了分析,制作了一个单频窄线宽掺镱光纤DBR激光器.在977 nm半导体激光器泵浦下,在1052.5 nm波长处输出功率可达4 mW,线宽小于8 MHz(受测量仪器分辨率限制).采用弧形梁调谐光纤光栅,实现了DBR光纤激光器在单纵模工作状态下的连续调谐,调谐范围可达20.4 nm(1036.1～1056.5 nm),并研究了调谐对激光器的泵浦阈值和斜率效率的影响.

| Abstract: | The characteristics of distributed Bragg reflector(DBR) cavity are analyzed. A narrow-linewidth single-frequency ytterbium-doped fiber DBR laser is fabricated. The laser is pumped by a semiconductor laser operated at 977 nm. Its output power reaches 4 mW and the lasing linewidth is less than 8 MHz (instrument resolution limited) at free wavelength of 1052.5 nm. Up to 20.4 nm(1036.1-1056.5 nm) continuous tuning is demonstrated from this DBR fiber laser operating in single longitudinal mode using a simple beam bending tuning technique for axial extension and compression. Over the full tuning range, threshold pump power and slope efficiency vary with laser wavelength. |
