從8字形全保偏飛秒摻鉺光纖雷射的剔除埠擷取雷射脈衝

Extraction of Laser Pulses from All-PM Figure-8 Femtosecond Erbium-Doped Fiber Laser

摘要


這篇技術論文介紹創新8字形全保偏飛秒摻鉺光纖雷射的輸出耦合方法,在8字形雷射腔的單一方向環中使用偏極分光鏡以及法拉第旋轉器,我們可以從全保偏摻鉺光纖雷射的剔除埠擷取雷射脈衝輸出到雷射腔外,回收利用了傳統8字形雷射中被浪費掉的雷射能源,從重複率112 MHz的摻鉺光纖雷射振盪器中,可以輸出23 mW的平均功率,這是利用NOLM/NALM技術鎖模的全保偏光纖雷射所報導過最高的輸出功率。

This paper proposes an innovative output coupling method for all-PM figure-8 femtosecond fiber laser. In the unidirectional loop of a figure-8 fiber laser, a polarization beam splitter and a Farady rotator is used to extract the laser pulses from the rejection port. The wasted pulse energy produced by traditional figure-8 fiber laser can be saved. An average power of 23 mW is obtained from the fiber laser oscillator with a repetition rate of 112 MHz, which is the highest output power ever recorded through the use of NOLM/NALM mode-locked fiber laser.
