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.

用于在 1550 nm 区域产生 Q 开关脉冲的碳酸钠

摘要

在这项研究中,我们通过实验证明了碳酸钠 (Na2CO3) 薄膜可作为可饱和吸收体 (SA),用于在掺铒光纤激光器 (EDFL) 腔中产生 Q 开关激光。Na 2 CO 3 粉末嵌入聚乙烯醇(PVA)中以制造薄膜。然后在 EDFL 腔中使用Na 2 CO 3以被动地产生最小脉冲宽度为 1.2 µs 和最大重复频率为 94.7 kHz 的 Q 开关脉冲。94.7 kHz的基频具有73.51 dB的信噪比,这表明脉冲是稳定的。Q 开​​关激光器在 1560 nm 的中心波长下工作。
