We report the first experiment on single-shot femtosecond laser ablation of monolayer hexagonal boron nitride (hBN). The observed intrinsic ablation threshold fluence is nearly 660 mJ/cm 2 , which is at least 10× higher than all other two-dimensional materials. Our work indicates the feasibility of hBN for femtosecond laser patterning.
