Comparison on different repetition rate locking methods in Er-doped fiber laser

Abstract

We demonstrate a systematic comparative research on the all-optical, mechanical and optomechanical repetition rate control methods in an Er-doped fiber laser. A piece of Yb-doped fiber, a piezoelectric transducer and an electronic polarization controller are simultaneously added in the laser cavity as different cavity length modulators. By measuring the cavity length tuning ranges, the output power fluctuations, the temporal and frequency repetition rate stability, we show that all-optical method introduces the minimal disturbances under current experimental condition.

“…According to the classification based on the gain medium, mode-locked fiber lasers can be categorized into Er-doped mode-locked fiber lasers [27][28][29][30][31][32][33], Yb-doped mode-locked fiber lasers [34][35][36][37][38], Tm-doped mode-locked fiber lasers [39][40][41][42], and so on. Among them, Er-doped mode-locked fiber lasers have gained considerable attention from researchers for several reasons.…”
