Saturable Absorption of Copper Nanowires in Visible Regions for Short-Pulse Generation
Published 2016-01-01Get full textA copper-nanowire (CuNWs)-based saturable absorber (SA) is utilized as a new Q-switcher for pulsed operations in visible regions. The plasmon resonance effect of CuNWs contributes to inducing the saturable absorption property. By incorporating the CuNWs-based SA into a red praseodymium <inline-fo...

Whispering-Gallery-Mode Resonator-Based Hybrid Cavity for Mode Stabilization of a Fiber Laser
Published 2021-01-01Get full textThe performances of a fiber laser stabilized by a whispering-gallery-mode(WGM) resonator depends heavily on the coupling of the resonator and fiber system, and is labile due to the lasing mode competitions among excitable WGMs. Here, we propose a hybrid cavity where a linear fiber cavity is coupled...

Efficient and Compact Diode-Pumped Nd:YAG Lasers at 1073 and 1078 nm
Published 2016-01-01Get full textWe report on the efficient diode-pumped continuous-wave laser operation of a Nd:YAG crystal at several wavelengths by using a simple and compact two-mirror laser cavity and an undoped YAG thin plate acting as a Fabry-Pérot (F-P) etalon. We thus obtain a high-power single-wavelength laser...

Passive Q-Switching of a Diode-Pumped Pr:LiYF<sub>4</sub> Visible Laser Using WS<sub>2</sub> as Saturable Absorber
Published 2016-01-01Get full textQ-switched laser operation of a blue-diode-pumped Pr:LiYF<sub>4</sub> laser is demonstrated at 640 nm for the first time by using a tungsten disulfide (WS<sub>2</sub>) nanosheet material as a saturable absorber. Stable laser pulses of 630 ns are obtained with a pulse repetiti...

0.1–1-THz High-Repetition-Rate Femtosecond Pulse Generation From Quasi-CW Dual-Pumped All-Fiber Phase-Locked Kerr Combs
Published 2016-01-01Get full textWe report the generation of tunable high-repetition-rate (0.1–1 THz) femtosecond pulses based on a quasi-continuous wave (CW) dual-pumped all-fiber cascaded four-wave-mixing (FWM) scheme without requiring a cavity resonator. By synchronously injecting two pulse-modulated lasers into an 85...
