Abstract

This paper experimentally demonstrates the use of a zinc oxide (ZnO) nanolaminate as a polarization-dependent loss element to control the frequency repetition rate in a passive mode-locked fiber laser. The ZnO nanolaminate was deposited via the atomic layer deposition technique. The system achieves repetition frequencies ranging from 2.2 to 6.6 MHz, with emission peaks occurring at wavelengths between 1569.1 nm and 1570.8 nm, exhibiting three to four peaks. The fiber exhibits a minimal pulse duration of around 9.78 ns; the maximal pulse-to-pulse separation was 452 ns. The fiber laser demonstrates excellent stability in both power and wavelength emission. The compact experimental setup leverages the properties of the thin film of zinc oxide, offering a versatile laser system capable of quickly altering pulse repetition rates by simply adjusting the polarization state.

使用氧化锌纳米层压板的可调重复率模式锁定光纤激光器

本文通过实验展示了如何利用氧化锌（ZnO）纳米层作为偏振相关损耗元件来控制无源模式锁定光纤激光器的频率重复率。氧化锌纳米层压板是通过原子层沉积技术沉积而成的。该系统的重复频率为 2.2 至 6.6 MHz，发射峰值出现在 1569.1 nm 至 1570.8 nm 波长之间，并呈现三至四个峰值。光纤的最小脉冲持续时间约为 9.78 ns，最大脉冲间隔为 452 ns。光纤激光器在功率和波长发射方面都表现出卓越的稳定性。紧凑的实验装置充分利用了氧化锌薄膜的特性，提供了一个多功能激光系统，只需调整偏振态，就能快速改变脉冲重复率。

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.
