| description | In this paper, we propose a novel ultrafast laser with nanostructure CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> nanorods, yielding a higher modulation depth and lower optical loss. Our experiment is performed through nanopatterned CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> rods and an all-solid-state passive mode-locked laser system. The prepared nanoarray CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> perovskite exhibits a modulation depth of 8.1% under a saturation intensity of 9.53 MW/cm<sup>2</sup>. By applying the CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> nanoarray as a saturable absorber in the ultrafast 1064-nm laser system, a mode-locked pulse with a 30-ps pulse width and an 87.3-MHz repetition rate is achieved. A maximum output power of 542 mW was measured, under an absorption pump power of 5.4 W. With the new structured CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>, our experiment verifies a new method in ultrafast lasers with low light loss, which potentially uncovers an avenue to develop ultrafast lasers. |
