Filamentation in low pressure conditions

open access: yesScientific Reports, 2022
AbstractFilamentation is favorable for many long-range outdoor laser applications, some of which require propagation to or at high altitudes. Understanding how the filamentation process and filament properties are impacted by the low pressure conditions present at high altitudes is essential in designing effective applications.
