A laser fence is a mechanism to detect objects passing the line of sight between the laser source and the detector.[1] Stronger lasers can potentially be used to injure someone or something passing the laser beam (see mosquito laser[2]).
Sometimes laser fences are used in fiction with the ability to stop intruders by blocking or injuring them.[citation needed]
Border fences
The Indian Border Security Force (BSF) has implemented a LASER wall system, called LASER Wall, along some parts of its border to stop intrusion. [3]
Films
In the 1992 film Fortress prisoners are kept secured by laser walls.
Videogames
It is a concept used frequently in videogames.[4] The concepts of these fictional fences can be compared to other concepts like tractor or repulsor beams.
Deus Ex: Human Revolution has laser grids which you can't get past without getting a Remote Hacking augmentation, allowing you to affect it. [5]
