Mode-locked Tm fiber laser using SMF-SIMF-GIMF-SMF fiber structure as a saturable absorber

Optics Express (2017)

Huanhuan Li Zhaokun Wang Can Li Junjie Zhang Shiqing Xu

We demonstrate a mode-locked all-fiber Tm laser using a single mode-step index multimode-graded-index multimode-single mode fiber structure as a saturable absorber based on the nonlinear multimodal interference. Stable fundamentally mode-locking operation was obtained at a pump threshold of 180mW. The output soliton pulses had a center wavelength, spectral width, pulse duration, and repetition rate of 1888 nm, 3.6 nm, 1.4 ps, and19.82 MHz, respectively. This is a simple, low-cost, stable, and convenient laser oscillator with many potential applications in eye-safe ultrafast photonics.

Generation of Controllable Bound Solitons from a Thulium–Holmium Co-Doped Mode-Locked Fiber Laser

SSRN Electronic Journal (2021)

Xinghao Ren Huanhuan Li Weiyang Chen Hao Jiang Can Li

The characteristics of wavelength tuning and pulse separation changing of soliton pairs at 2 μm are still largely unexploited although they are helpful for the application of bound states in the field of high-capacity soliton fiber communication systems. We report on the experimental observations of stable single solitons and bound solitons in a thulium–holmium co-doped passively mode-locked fiber laser by using the nonlinear polarization rotation technology. At a fixed pump power, the stable single soliton operation is converted to the soliton pair operation by cautiously adjusting the polarization controllers. Tightly bound soliton pairs with continuously tunable wavelengths from 1960.48 nm to 1989.45 nm, with a soliton separation of ∼4 ps, are observed. Meanwhile, several different pulse separations from 5.2 ps to 11.2 ps of soliton pairs are also realized. With the increasing pump power, a triple-soliton bound state is also observed. The results help in understanding the nonlinear dynamics of fiber lasers.

Optical parametric amplifier at 1572nm wavelength using KTiOAsO₄crystal

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2013)

Huanhuan Li Shiguang Li Xiuhuan Ma Juntao Wang Xiaolei Zhu

We report on a nanosecond master oscillator /power amplifier architecture for optical parametric conversion of high pulse energy from 1.064μm to 1.572 μm in KTiOAsO4 crystal. The signal emission is amplified by two different parametric amplifier architectures respectively. By comparing the results obtained, a novel amplifier architecture is chosen which is expected to combine the high gain and good beam quality. With a seeding signal energy of 1 mJ, and 400mJ pump pulse at 100Hz, a gain up to 64 at 1.57μm with the beam quality M² less than 4.8 is realized. The total optical-optical conversion efficiency reached 16%.
