摘要
In this paper,a conventional soliton(CS)mode-locked erbium-doped fiber(EDF)laser was de-veloped using MAX phase material(MAX-PM)Nb_(4)AlC_(3)as a saturable absorber(SA).First,the liquid phase exfoliation(LPE)method was utilized to prepare Nb_(4)AlC_(3)nanosheets,and then a piece of tapered fiber was adopted to fabricate Nb_(4)AlC_(3)-SA.It was found that the saturation intensity and modulation depth of the Nb_(4)AlC_(3)-SA are 2.02 MW/cm^(2)and 1.88%.Based on the Nb_(4)AlC_(3)-SA,a conventional soliton(CS)mode-locked EDF laser was achieved.The central wavelength,pulse duration,and pulse repetition rate were found to be 1565.65 nm,615.37 fs,and 24.63 MHz,respectively.The performance is competitive and particularly superior in terms of pulse duration.This study fully confirms that Nb_(4)AlC_(3)possesses marvellous nonlinear saturable absorption properties and opens new possibilities for further research on air-stable ultrafast photon-ic devices.
本文采用MAX相(MAX-PM)材料Nb_(4)AlC_(3)作为可饱和吸收体(SA),研制了传统孤子(CS)锁模掺铒光纤(EDF)激光器。首先,利用液相剥离(LPE)法制备了Nb_(4)AlC_(3)纳米片,然后采用拉锥光纤制作了Nb_(4)AlC_(3)-SA。该Nb_(4)AlC_(3)可饱和吸收体的饱和强度和调制深度分别为2.02 MW/cm^(2)和1.88%。基于所制备的Nb_(4)AlC_(3)可饱和吸收体,研制了传统孤子锁模掺铒光纤激光器。该激光器的中心波长、脉冲持续时间和脉冲重复率分别为1565.65 nm、615.37 fs和24.63 MHz。该锁模激光器性能优越,特别是在脉冲持续时间方面表现优异。本研究充分证实Nb_(4)AlC_(3)具有优异的非线性可饱和吸收特性,同时也为空气稳定型超快光子器件的深入研究拓宽了途径。
