Through a liquid-phase synthesis route, zeolitic imidazolate framework-67 (ZIF-67) nanomaterials are prepared and deposited onto a quartz glass to form a new type of saturable absorber (SA), of which nonlinear optical (NLO) properties are measured at a wavelength of 2 μm with a homemade nanosecond pulsed laser. The result shows that the ZIF-67 sample exhibits an excellent NLO response. As an application, a stable passively Q-switched (PQS) 2 μm solid-state laser with ZIF-67 as a SA was demonstrated. The pulsed laser with a minimum pulse width of 278 ns at a repetition frequency of 131 kHz was generated via an output coupler (OC) of 5% transmittance, corresponding to a maximum single-pulse energy of 1.5 μJ. It is the first presentation of a 2 μm solid-state PQS laser with ZIF-67 utilized as a modulator, to the best of our knowledge. Taking into account the laser performance in experiments, ZIF-67 is shown to be a novel nanomaterial for the application of a modulator for mid-infrared (MIR) pulse generation.

沸石咪唑盐骨架67纳米晶体的中红外脉冲产生的非线性光学特性

通过液相合成路线，制备了沸石咪唑盐骨架67（ZIF-67）纳米材料，并将其沉积在石英玻璃上以形成新型的可饱和吸收剂（SA），该吸收剂的非线性光学（NLO）性能在60℃下测量。自制的纳秒脉冲激光的波长为2μm。结果表明，ZIF-67样品表现出出色的NLO响应。作为应用，展示了稳定的无源Q开关（PQS）2μm固态激光器，其中ZIF-67作为SA。经由5％透射率的输出耦合器（OC）产生的脉冲激光的最小脉冲宽度为278 ns，重复频率为131 kHz，对应最大单脉冲能量为1.5μJ。据我们所知，这是首次使用ZIF-67作为调制器的2μm固态PQS激光器。
