Abstract

We have prepared the

graphene / {MoS}_{2}

heterostructure by a hydrothermal method, and presented its nonlinear absorption parameters and application as a nonlinear optical modulator in the mid-infrared region. Using the nonlinear optical modulator, stable passively Q-switched operation of an

{Er}^{3 +}

-doped

{ZrF}_{4} - {BaF}_{2} - {LaF}_{3} - {AlF}_{3} - NaF

(ZBLAN) fiber laser at

～ 2.8 μ m

can be obtained. The Q-switched

{Er}^{3 +}

-doped ZBLAN fiber laser can yield per-pulse energy up to 2.2 μJ with the corresponding pulse width and pulse repetition rate of 1.9 μs and 45 kHz, respectively. Our results indicate that the
