摘要

介绍了一种基于单片主振荡器功率放大器（MOPA）系统的高功率、窄带皮秒掺铥光纤激光器。种子源采用SESAM锁模掺铥光纤激光器，平均输出功率为3.5 mW，重复频率为14.77 MHz。经过4级掺铥放大器后，平均输出功率达到10.01 W，无明显的自发发射放大现象。脉冲宽度为10.7 ps，单脉冲能量为677.7 nJ，峰值功率为63.3 kW。输出光谱的中心波长为1906.5 nm，光谱带宽较窄，为0.6 nm。据我们所知，这是迄今为止报道的皮秒掺铥全光纤MOPA系统在1908 nm附近的最高平均功率。

10-W-level picosecond thulium-doped all-fiber MOPA system at 1906 nm with narrow spectral bandwidth

A high-power, narrow-bandwidth picosecond thulium-doped fiber laser operating at 1906 nm is demonstrated based on a monolithic master oscillator power amplifier (MOPA) system. A SESAM mode-locked thulium-doped fiber laser is used as the seed source with an average output power of 3.5 mW at a repetition rate of 14.77 MHz. After a four-stage thulium-doped amplifier, the average output power reaches 10.01 W without obvious amplified spontaneous emission (ASE). The pulse width and the single pulse energy are 10.7 ps and 677.7 nJ respectively, corresponding to a peak power of 63.3 kW. The center wavelength of the output spectrum is 1906.5 nm with a narrow spectral bandwidth of 0.6 nm. To the best of our knowledge, this is the highest average power ever reported for a picosecond thulium-doped all-fiber MOPA system near 1908 nm.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
