摘要

在这项工作中，我们展示了一种全光纤配置的 Q 开关掺钕光纤激光器（NDFL），该激光器利用酞菁铁（FePc）作为可饱和吸收体（SA）。通过浸渍工艺将市售的铁酞菁粉末沉积到套圈的尖端，从而有效地制备出铁酞菁 SA 器件。将这种 FePc SA 器件集成到 NDFL 腔中，可产生最短持续时间为 3.29 µs、最高频率为 45.50 kHz 的稳定 Q 开关脉冲。该激光器的工作波长为 1089.0 nm，在 808 nm 波长的最大泵浦功率为 189.56 mW 时，脉冲能量为 71.43 nJ，输出功率为 3.25 mW。这是基于 FePc 的 Q 开关 NDFL 在 1 µm 波长区域工作的首次演示。

Q-switched neodymium doped all-fiber laser with iron phthalocyanines saturable absorber

In this work, we presented a Q-switched neodymium-doped fiber laser (NDFL) utilizing iron phthalocyanine (FePc) as a saturable absorber (SA) in an all-fiber configuration. The SA was effectively prepared by depositing commercially available FePc powder onto the tip of a ferrule using a dipping process, thereby creating the FePc SA device. Integrating this FePc SA device into the NDFL cavity resulted in stable Q-switched pulses with a minimum duration of 3.29 µs and a maximum frequency of 45.50 kHz. The laser operated at a wavelength of 1089.0 nm, delivering pulse energies of 71.43 nJ and an output power of 3.25 mW at a maximum pump power of 189.56 mW at 808 nm. This represents the first demonstration of a FePc-based Q-switched NDFL operating at 1 µm wavelength region.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
