Zirconium carbide (ZrC) with layered structure and nanoparticle morphology was prepared by sonication in an ethyl alcohol solvent. The morphology and saturable absorption properties of the ZrC were systematically analyzed. By using ZrC nanoparticle coated substrates as saturable absorbers, stable Q-switched 3 μm Er:Lu2O3 lasers were realized. Pulse durations of 50 ns with pulse energies of 20 μJ and peak power of 0.4 kW are the shortest obtained with novel-material-based Q-switched lasers in the 3 μm wavelength range.

ZrC的中红外调Q性能

通过在乙醇溶剂中超声处理制备具有层状结构和纳米颗粒形态的碳化锆 (ZrC)。系统地分析了 ZrC 的形貌和饱和吸收特性。通过使用 ZrC 纳米粒子涂层衬底作为可饱和吸收体，实现了稳定的 Q 开关 3 μm Er:Lu2O3 激光器。脉冲能量为 20 μJ、峰值功率为 0.4 kW 的脉冲持续时间为 50 ns，是基于新型材料的 Q 开关激光器在 3 μm 波长范围内获得的最短脉冲持续时间。
