基于石墨烯/WS2可饱和吸收体的中红外Er3+:ZBLAN锁模激光器及其波长可调谐性能
Mid Infrared Er3+:ZBLAN Mode-locked Laser and Wavelength Tunable Performance Based on Graphene/WS2 Saturated Absorber
摘要
Abstract
Graphene and transition metal sulfide WS2 have stable chemical properties and broadband absorption spectra,which can realize the pulse operation of laser in the mid-infrared band.This paper reports the application of graphene and WS2 as saturable absorbers in mode-locked lasers in mid-infrared band.Experiments show that gra-phene/WS2 composites have better nonlinear absorption characteristics,and exhibit low mode-locked threshold and high material damage threshold during mode-locked modulation.When the pump power is 5 W,The mode-locked pulse with pulse width of 24.04 ps was obtained at 2781.7 nm.The maximum average output power of the laser was 237.7 mW and the peak power was 395.5 W.Finally,the wavelength tunable output of the laser is realized by grat-ing,and the output wavelength of the graphene/WS2 mode-locked laser is widened to 2730-2810 nm.关键词
