Transition metal dichalcogenides are known to possess large optical nonlinearities, and
driving these materials at high intensities is desirable for many applications. Understanding
their optical responses under repetitive intense excitation is essential to improve the
performance limit of these strong-field devices and to achieve efficient laser patterning.
Here, we report the incubation study of monolayer MoS 2 and WS 2 induced by 160 fs, 800
nm pulses in air to examine how their ablation threshold scales with the number of admitted …
