| 摘 要： | 通过在非线性偏振旋转环形腔内引入一种可旋转的在线起偏器,在保证装置的全光纤化结构的前提下,简化了被动锁模光纤激光器的结构.通过联合调节可旋转的在线起偏器、1/2波片和1/4波片的角度实现了掺饵光纤锁模脉冲20 nm间隔的双波长调谐输出,调谐过程中观察到了锁模脉冲双波长状态.另外,从装置中去掉1/2波片后,仅调谐可旋转的在线起偏器和1/4波片也能够实现锁模脉冲的单波长稳定输出.

| Abstract: | By introducing the rotatable in-line polarizer into the ring cavity of nolinear polarization rotatation(NPR), the all fiber structure of passively mode-locked ring laser is simplified. The Erbium-doped mode-locked laser with the tuning range of 20 nm is achieved by adjusting the polarizer, 1/2 wave plate and the 1/4 wave plate together. Furthermore, the mode-locked pulses with dual-wavelength are observed during the tuning process. On the other hand, when removing the 1/2 wave plate from the configuration, the mode-locked laser can also be obtained by only adjusting the polarizer and the 1/4 wave plate. The tunable process is presented and analyzed. |
