Abstract

The saturation absorption characteristics of layered ternary transition metal carbide Ta₂AlC were investigated in this study. The passive mode-locking erbium-doped fiber laser (EDFL) was fabricated using Ta₂AlC saturable absorber (SA), which was prepared by depositing nanosheets on a tapered fiber. A conventional soliton (CS) with a repetition frequency of 5.25 MHz and a 3 dB bandwidth of 2.59 nm was obtained at pump powers ranging from 409 mW to 599 mW. At a pump power of 466 mW, third-order, fourth-order and fifth-order harmonic mode-locking (HML) were observed. The fifth-order HML exhibited a repetition frequency of 26.1 MHz, while the Six-pulse and Seven-pulse phenomena were observed to be stable. In addition, bound state solitons with a modulation period of 0.58 nm were obtained at a pump power of 447 mW. In this paper, Ta₂AlC generated an abundance of soliton states, which held significant implications for ultra-fast laser pulses and optical communications. It is evident that Ta₂AlC has excellent nonlinear optical characteristics, thereby offering remarkable performance and application prospects.

全光纤激光器中基于Ta2AlC饱和吸收体的丰富孤子态

研究了层状三元过渡金属碳化物Ta2AlC的饱和吸收特性。采用在锥形光纤上沉积纳米片的Ta2AlC可饱和吸收体（SA）制备了无源锁模掺铒光纤激光器（EDFL）。在409 ~ 599 mW的泵浦功率范围内，获得了一个重复频率为5.25 MHz、带宽为2.59 nm的常规孤子（CS）。在泵浦功率为466 mW时，观察到三阶、四阶和五阶谐波锁模（HML）。五阶HML的重复频率为26.1 MHz，而六脉冲和七脉冲现象是稳定的。此外，在447 mW的泵浦功率下，获得了调制周期为0.58 nm的束缚态孤子。在本文中，Ta2AlC产生了大量的孤子态，这对超高速激光脉冲和光通信具有重要意义。可见，Ta2AlC具有优良的非线性光学特性，具有显著的性能和应用前景。

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.
