I often wonder the same about the technology used in a mysterious video that appeared on youtube about 15 years ago titled "Laser Induced Plasma Channel".

It appears to be an area denial weapon that uses femtosecond lasers to guide electric arcs across a hallway (think a metre-long ridiculously straight Taser discharge).

The video had no description and comments on it were never answered - it was recently removed by the uploader, but there seems to be a reupload on DailyMotion[1] from 9 years ago.
