What is it about?
Semiconductor transition metal dichalcogenides are an important class of 2D materials for the miniaturization of future electronic devices due to their unique properties. For optical applications, understanding the limitations of these materials is important to optimize their performance for such devices. This paper examines the optical limitations and defects of these materials when excited by ultrafast pulses.

Why is it important?
The findings presented here show that semiconducting 2D materials, specifically MoS2, are some of the most optically robust materials and are able to resist optical damage when exposed to multiple intense pulses. Additionally, the onset of optical damage results in nano-size holes that significantly modify the optical properties of the material. This result demonstrates the applicabiity of these materials for applications requiring intense optical pulses.
