technology promises a generation of innovation in
cross-cutting subjects ranging from electronic skins, to wearable
electronics, to point-of-care biomedical sensing modules. Recently,
scientists have successfully pulled off significant advances in self-healing
components including sensors, energy devices, transistors, and even
integrated circuits. Lasers, one of the most important light sources,
integrated with autonomous self-healability should be endowed with
more functionalities and opportunities; however, the study of self-healing
lasers is absent in all published reports. Here, the soft and self-healable
random laser (SSRL) is presented. The SSRL can not only endure extreme
external strain but also withstand several cutting/healing test cycles.
Particularly, the damaged SSRL enables its functionality to be restored
within just few minutes without the need of additional energy, chemical/electrical
agents, or other healing stimuli, truly exhibiting a supple yet robust
laser prototype. It is believed that SSRL can serve as a vital building
block for next-generation laser technology as well as follow-on self-healing
optoelectronics.
