Laser Barrier

Laser Barriers are mounted on doors. They are activated by nearby Security Cameras that detect any hostile targets (a player). Trying to pass through the barrier will deal high damage to shields, knock the player down, and push them back (unlucky players may not be pushed away, subjecting them to additional damage). Corpus are able to pass through these barriers and will occasionally stand in the way, leaving an opening players can walk through while it is still active.

Dodging Techniques
The following skills will allow warframes to pass through Laser Barriers unharmed:
 * Excalibur's "Slash Dash"
 * Rhino's "Rhino Charge"
 * Loki's "Switch Teleport" or "Decoy,"
 * Trinity's "Link"

Mag can also pull other players through without them being harmed.

In addition, jumping during a slide just before contacting the barrier will usually result in bypassing it completely, taking no damage or knockback. This is most likely a glitch, and may be fixed in a later patch.

Another known technique for bypassing laser barriers without taking damage is the "Phantom Cut," where during a slide, a melee attack is done. During the melee attack, the Warframe should dash forward, and if timed correctly, the attack will pass through the lasers without the Warframe taking any damage.
