| 1 | 35 W continuous-wave Ho:YAG single-crystal fiber laser显示文摘We report on a high-power Ho:YAG single-crystal fiber(SCF)laser inband pumped by a high-brightness Tm-fiber laser at 1908 nm.The Ho:YAG SCF grown by the micro-pulling-down technique exhibits a propagation loss of 0.05±0.005 cm^-1 at 2.09μm.A continuous-wave output power of 35.2 W is achieved with a slope efficiency of 42.7%,which is to the best of our knowledge the highest power ever reported from an SCF-based laser in the 2µm spectral range. | Yongguang Zhao Li Wang Weidong Chen Jianlei Wang Qingsong Song Xiaodong Xu Ying Liu Deyuan Shen Jun Xu Xavier Mateos Pavel Loiko Zhengping Wang Xinguang Xu Uwe Griebner Valentin Petrov | 2020 | High Power Laser Science and Engineering2020，8，2： | 7 |
| 2 | Generation of 84-fs pulses from a mode-locked Tm:CNNGG disordered garnet crystal laser显示文摘A mode-locked laser based on a Tm:CNNGG disordered crystal as an active medium and a single-walled carbon nanotube saturable absorber is demonstrated, operating at a central wavelength of 2018 nm. Transformlimited 84 fs pulses are generated with an average output power of 22 mW at a repetition rate of ~90 MHz.A maximum output power of 98 mW is obtained at a slightly longer pulse duration of 114 fs. | ZHONGBEN PAN YICHENG WANG YONGGUANG ZHAO HUALEI YUAN XIAOJUN DAI HUAQIANG CAI JI EUN BAE SUN YOUNG CHOI FABIAN ROTERMUND XAVIER MATEOS JOSEP MARIA SERRES PAVEL LOIKO UWE GRIEBNER VALENTIN PETROV | 2018 | Photonics Research2018，6，8： | 4 |
| 3 | Structured laser beams: toward 2-μm femtosecond laser vortices显示文摘Structured ultrashort-pulse laser beams, and in particular eigenmodes of the paraxial Helmholtz equation, are currently extensively studied for novel potential applications in various fields, e.g., laser plasma acceleration,attosecond science, and fine micromachining. To extend these prospects further, in the present work we push forward the advancement of such femtosecond structured laser sources into the 2-μm spectral region. Ultrashortpulse Hermite– and Laguerre–Gaussian laser modes both with a pulse duration around 100 fs are successfully produced from a compact solid-state laser in combination with a simple single-cylindrical-lens converter. The negligible beam astigmatism, the broad optical spectra, and the almost chirp-free pulses emphasize the high reliability of this laser source. This work, as a proof of principle study, paves the way toward few-cycle pulse generation of optical vortices at 2 μm. The presented light source can enable new research in the fields of interaction with organic materials, next generation optical detection, and optical vortex infrared supercontinuum. | Yongguang Zhao Li Wang Weidong Chen Pavel Loiko Xavier Mateos Xiaodong Xu Ying Liu Deyuan Shen Zhengping Wang Xinguang Xu Uwe Griebner Valentin Petrov | 2021 | Photonics Research2021，9，3： | 3 |

| 5 | Power-scalable sub-100-fs Tm laser at 2.08μm显示文摘We report on a power-scalable sub-100-fs laser in the 2-μm spectral range using a Tm;-doped‘mixed’(Lu,Sc);O;sesquioxide ceramic as an active medium.Pulses as short as 58 fs at 2076 nm with an average output power of 114 mW at a pulse repetition rate of approximately 82.9 MHz are generated by employing single-walled carbon nanotubes as a saturable absorber.A higher average power of 350 m W at 2075 nm is obtained at the expense of the pulse duration(65 fs).A maximum average power of 486 mW is achieved for a pulse duration of 98 fs and an optical conversion efficiency of 22.3%,representing the highest value ever reported from sub-100-fs mode-locked Tm lasers. | Li Wang Weidong Chen Yongguang Zhao Hanlin Yang Wei Jing Zhongben Pan Hui Huang Jiachen Liu Ji Eun Bae Fabian Rotermund Pavel Loiko Xavier Mateos Zhengping Wang Xinguang Xu Uwe Griebner Valentin Petrov | 2021 | High Power Laser Science and Engineering2021，9，4： | 1 |

| 12 | Passively Q-switched femtosecond-laser-written thulium waveguide laser based on evanescent field interaction with carbon nanotubes显示文摘Surface channel waveguides(WGs) were fabricated in a monoclinic Tm^(3+):KLu(WO_4)_2 crystal by femtosecond direct laser writing(fs-DLW). The WGs consisted of a half-ring cladding with diameters of 50 and 60 μm located just beneath the crystal surface. They were characterized by confocal laser microscopy and μ-Raman spectroscopy,indicating a reduced crystallinity and stress-induced birefringence of the WG cladding. In continuous-wave(CW)mode, under Ti:sapphire laser pumping at 802 nm, the maximum output power reached 171.1 mW at 1847.4 nm,corresponding to a slope efficiency η of 37.8% for the 60 μm diameter WG. The WG propagation loss was0.7 0.3 d B∕cm. The top surface of the WGs was spin-coated by a polymethyl methacrylate film containing randomly oriented(spaghetti-like) arc-discharge single-walled carbon nanotubes serving as a saturable absorber based on evanescent field coupling. Stable passively Q-switched(PQS) operation was achieved. The PQS60 μm diameter WG laser generated a record output power of 150 m W at 1846.8 nm with η = 34.6%. The conversion efficiency with respect to the CW mode was 87.6%. The best pulse characteristics(energy/duration)were 105.6 nJ/98 ns at a repetition rate of 1.42 MHz. | ESROM KIFLE PAVEL LOIKO JAVIER RODRíGUEZ VáZQUEZ DE ALDANA CAROLINA ROMERO AIRáN RóDENAS SUN YUNG CHOI JI EUN BAE FABIAN ROTERMUND VIKTOR ZAKHAROV ANDREY VENIAMINOV MAGDALENA AGUILó FRANCESC DíAZ UWE GRIEBNER VALENTIN PETROV XAVIER MATEOS | 2018 | Photonics Research2018，6，10： | 1 |
