N2  - In this paper, the formation of laser-induced periodic surface structures
(LIPSS) on atomic-layer deposited MoS 2 layers are studied experimentally. The
process parameters (laser fluence and the pulse overlap) corresponding to
formation of low- and high-spatial frequency LIPSS as well as ablation and
modification of the layers are identified for different pulse durations in the
range from 0.2 to 10 ps. The role of the temperature accumulation is evaluated by changing the repetition rate from 0.2 to 2 MHz. The negative accumulation effect, i.e., the ablation of the layers becomes more difficult at higher laser pulse overlaps, is also observed. A simple model explaining the transition between different types of the LIPSS and the decrease of the ablation efficiency with the pulse overlap is suggested.
