Abstract

ABSTRACT We demonstrate the generation of Q-switching pulse train in thulium-doped fiber laser (TDFL) cavity by employing titanium-based saturable absorber (Ti-SA). The Ti-SA was fabricated by depositing titanium particles molecules using electron beam evaporation on the surface of a polyvinyl alcohol (PVA) film. Subsequently, stable Q-switched pulses were obtained within the 1,552 nm pump power range from 272.1 to 467 mW, with repetition rate tuned from 21.8 to 39.1 kHz. At the maximum pump power, the TDFL showed that the pulse duration of 2.22 μs and the maximum pulse energy of 124 nJ.

纯钛膜基饱和吸收器调q掺铥光纤激光器

研究了利用钛基可饱和吸收剂(Ti-SA)在掺铥光纤激光器(TDFL)腔中产生调q脉冲串。采用电子束蒸发法将钛颗粒分子沉积在聚乙烯醇(PVA)薄膜表面，制备了Ti-SA。随后，在1552 nm泵浦功率范围(272.1 ~ 467 mW)内获得了稳定的调q脉冲，重复频率在21.8 ~ 39.1 kHz之间调谐。在最大泵浦功率下，TDFL脉冲持续时间为2.22 μs，最大脉冲能量为124 nJ。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
