摘要

We demonstrate pulsewidth tunable Q-switched erbium fiber lasers using in-line high extinction ratio (>30 dB) abrupt-tapered fiber Mach-Zehnder block filter and tunable Fabry-Perot filter in laser cavity. The pulsewidth can be tuning over 78 ns - 23 ms.
[GRAPHICS]
Q-switched pulse shape with pulsewidth and repetition rate at 1.84 mu s, 60.
