| 1 | Few-layer MoS2 grown by chemical vapor deposition as a passive Q-switcher for tunable erbium-doped fiber lasers显示文摘We report an erbium-doped fiber laser passively Q-switched by a few-layer molybdenum disulfide(MoS2) saturable absorber(SA).The few-layer MoS2 is grown by the chemical vapor deposition method and transferred onto the end-face of a fiber connector to form a fiber-compatible MoS2 SA.The laser cavity is constructed by using a three-port optical circulator and a fiber Bragg grating(FBG) as the two end-mirrors.Stable Q-switched pulses are obtained with a pulse duration of 1.92 μs at 1560.5 nm.By increasing the pump power from 42 to 204 mW,the pulse repetition rate can be widely changed from 28.6 to 114.8 kHz.Passive Q-switching operations with discrete lasing wavelengths ranging from 1529.8 to 1570.1 nm are also investigated by using FBGs with different central wavelengths.This work demonstrates that few-layer MoS2 can serve as a promising SA for wideband-tunable Q-switching laser operation. | Handing Xia Heping Li Changyong Lan Chun Li Jinbo Du Shangjian Zhang Yong Liu | 2015 | Photonics Research2015，3，3： | 2 |
| 2 | Two-Dimensional Tunable and Temperature-Insensitive Lyot Filter for FM-to-AM Compensation显示文摘Utilizing polarization maintaining photonic crystal fiber(PM-PCF)with the low temperature coefficient of birefringence,a two-dimensional tunable and temperature-insensitive Lyot filter aiming to compensate the frequency modulation to amplitude modulation(FM-to-AM)conversion in high power laser facility is demonstrated.The Jones matrix is applied to analyze the relationship between optical characteristics of the filter and physical parameters(including amplitude ratio,phase delay,and susceptibility of the birefringence to temperature)of the polarization optical field.Both the transmission peak wavelength and extinction ratio of the spectral transmission are able to be changed simultaneously,hence,it shows more efficient FM-to-AM compensation ability.Besides,the transmission peak shift is about 18pm/°C with the PM-PCF configuration,which is about two orders of magnitude less than the normal polarization maintaining fiber(PMF)configuration.The demonstrated filter presents a practical application potential in large scale laser driven facility. | Mengqiu Fan Xiaocheng Tian Dandan Zhou Jiatian Wei Handing Xia Hongwei Lv Hao Zhao Dangpeng Xu Wanguo Zheng | 2021 | Photonic Sensors2021，11，3： | 1 |
| 3 | Corrigendum to:“Spectrum-tailored random fiber laser towards ICF laser facility”[Matter and Radiation at Extremes 8,025902(2023)]显示文摘The third paragraph in Sec.IV REGENERATIVE AMPLIFICATION erroneously states“In other words,the distribution of spectral components is time-dependent,and the spectral distortion in the amplification process will not change the time-domain shape.” | Mengqiu Fan Shengtao Lin Ke Yao Yifei Qi Jiaojiao Zhang Junwen Zheng Pan Wang Longqun Ni Xingyu Bao Dandan Zhou Bo Zhang Kaibo Xiao Handing Xia Rui Zhang Ping Li Wanguo Zheng Zinan Wang | 2023 | Matter and Radiation at Extremes2023，8，2： | 1 |
| 4 | Spectrum-tailored random fiber laser towards ICF laser facility显示文摘Broadband low-coherence light is considered to be an effective way to suppress laser plasma instability.Recent studies have demonstrated the ability of low-coherence laser facilities to reduce back-scattering during beam–target coupling.However,to ensure simultaneous low coherence and high energy,complex spectral modulation methods and amplification routes have to be adopted.In this work,we propose the use of a random fiber laser(RFL)as the seed source.The spectral features of this RFL can be carefully tailored to provide a good match with the gain characteristics of the laser amplification medium,thus enabling efficient amplification while maintaining low coherence.First,a theoretical model is constructed to give a comprehensive description of the output characteristics of the spectrum-tailored RFL,after which the designed RFL is experimentally realized as a seed source.Through precise pulse shaping and efficient regenerative amplification,a shaped random laser pulse output of 28 mJ is obtained,which is the first random laser system with megawatt-class peak power that is able to achieve low coherence and efficient spectrum-conformal regenerative amplification. | Mengqiu Fan Shengtao Lin Ke Yao Yifei Qi Jiaojiao Zhang Junwen Zheng Pan Wang Longqun Ni Xingyu Bao Dandan Zhou Bo Zhang Kaibo Xiao Handing Xia Rui Zhang Ping Li Wanguo Zheng Zinan Wang | 2023 | Matter and Radiation at Extremes2023，8，2： | 0 |
