TL;DR
This paper investigates the electrical conductivity and discharge guiding abilities of mid-infrared laser filaments at 3.9 micrometers in air, comparing them to near-infrared filaments for potential lightning control applications.
Contribution
It provides the first detailed comparison of mid-IR and near-IR laser filaments' electrical and discharge guiding properties under identical conditions.
Findings
Mid-IR filaments exhibit distinct conductivity characteristics.
Mid-IR filaments can trigger and guide high-voltage discharges.
Comparison shows potential advantages of mid-IR for lightning control.
Abstract
The electric conductivity, HV discharge triggering and guiding capabilities of filaments at 3.9 micrometer in air are investigated in the perspective of lightning control applications, and compared to near-IR filaments in identical conditions
