Abstract

ABSTRACT In this study, we have experimentally demonstrated the sodium carbonate (Na₂CO₃) thin-film as a saturable absorber (SA) for Q-switched laser generation in erbium-doped fiber laser (EDFL) cavity. The Na₂CO₃ powder was embedded in polyvinyl alcohol (PVA) to fabricate the thin film. The Na2CO3 was then employed in an EDFL cavity for passively generating Q-switched pulses with a minimum pulse width of 1.2 µs and maximum repetition rate of 94.7 kHz. The fundamental frequency of 94.7 kHz had the signal to noise ratio of 73.51 dB, which indicates the pulses were stable. The Q-switched laser operated at center wavelength of 1560 nm.

碳酸钠在1550nm区域产生调q脉冲

在这项研究中，我们实验证明了碳酸钠(Na₂CO₃)薄膜作为可饱和吸收剂(SA)用于在掺铒光纤激光器(EDFL)腔中产生调q激光。将Na₂CO₃粉末包埋在聚乙烯醇(PVA)中，制成薄膜。然后在EDFL腔中使用Na2CO3被动产生最小脉冲宽度为1.2µs，最大重复频率为94.7 kHz的调q脉冲。基频为94.7 kHz，信噪比为73.51 dB，表明脉冲稳定。调q激光器工作在1560nm的中心波长。

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.
