Abstract

A single-oscillator actively Q-switched mode-locked (QML) thulium-doped silica fiber laser is presented and used to pump a ZrF-BaF-LaF-AlF-NaF (ZBLAN) fiber for mid-infrared (mid-IR) supercontinuum (SC) generation. The fiber laser provided high-peak-power levels directly from the oscillator delivering single mode-locked pulse energies up to 48 μJ, being 2-4 orders of magnitude higher than conventional continuous wave mode-locked lasers. By pumping a ZBLAN fiber specially designed for high-output-power SC generation, 7.8 W have been achieved in all spectral bands with a spectrum extending to 4.2 μm.

摘要

本文介绍了一种单振荡器主动调Q锁模（QML）掺铥石英光纤激光器，并将其用于泵浦ZrF-BaF-LaF-AlF-NaF（ZBLAN）光纤以产生中红外（mid-IR）超连续谱（SC）。该光纤激光器直接从振荡器提供高峰值功率，输出单锁模脉冲能量高达48 μJ，比传统连续波锁模激光器高2至4个数量级。通过泵浦专门为高输出功率SC产生而设计的ZBLAN光纤，在所有光谱波段实现了7.8 W的输出，光谱延伸至4.2 μm。
