  • Long lifetime plasma flares by laser breakdown of air with intense RF heating
    Patent number: 10104756
    Abstract: The system and method for creating plasma flares in air by using an ultra-short pulse laser (USPL) that generates plasma filaments with a short lifetime (in nanoseconds), and by heating these plasma filaments with intense microwave (RF) radiation to induce robust air breakdown, resulting in long lifetime (up to milliseconds) plasma flares in the atmosphere.
