TL;DR: In this paper, a tungsten disulfide (WS2) film SA fabricated by pulsed laser deposition (PLD) method was used to achieve stable fundamental mode-locking at pump power of 54 mW, and the generated soliton pulse had pulse duration of 675 fs and signal-to-noise ratio (SNR) of 65 dB.
Journal ArticleDOI
Passively mode-locked fiber laser by a cell-type WS2 nanosheets saturable absorber.
TL;DR: The results demonstrate that the cell-type WS2 nanosheets SA can serve as a good candidate for short-pulse mode locker.
Journal ArticleDOI

Peiguang Yan,Rongyong Lin,Shuangchen Ruan,Aijiang Liu,Hao Chen,Yuequn Zheng,Sifan Chen,Chunyu Guo,Juguang Hu +8 more
TL;DR: A novel saturable absorber was fabricated by coating the topological insulator (TI) film on microfiber using pulsed laser deposition (PLD) method and it is shown that the PLD is an effective scheme for practical SA device fabrication.
Journal ArticleDOI
A 2.95 GHz, femtosecond passive harmonic mode-locked fiber laser based on evanescent field interaction with topological insulator film
TL;DR: The results demonstrated that the microfiber-based TI PLD film SA is a promising device for practical multi-GHz ultrashort pulses generation and proposed a newly explanation for the impact of nonlinear effect of SA on the harmonic mode-locking behavior.
Journal ArticleDOI
Topological Insulator Solution Filled in Photonic Crystal Fiber for Passive Mode-Locked Fiber Laser
TL;DR: In this article, the topological insulator (TI) nanosheets solution filled in photonic crystal fiber can operate as an effective saturable absorber (SA) with the merits of low insertion loss (sim 0.42$ dB), long interaction length (>10 cm), and high power tolerance.
