Beam lasers fire a sustained arc of energy that persists as long as the trigger is held down. Beam lasers have limited range and massive recoil save for Hyperion-Body variants.
Depending on the manufacturer of the laser's body, Beam lasers can spawn with manufacturer-specific gimmicks:
Dahl Beams fire in bursts when zoomed in and have reduced recoil. It also comes with the ability to penetrate through enemy targets, inflicting damage to several enemies at once. However they do not work well with Dahl's Burst Fire as they only consume 3 rounds which is never enough for the Beam's continuious damage purpose.
Hyperion Beams have their reverse recoil gimmick which offsets the massive recoil that it would have suffered otherwise. It also has a 50% bonus to critical hit damage (60% with a Hyperion stock).
Maliwan Beams have an increase in elemental damage and chance, making it reliable for inflicting elemental status effects. It also has a continuous damage bonus that deals more damage the longer the trigger is held. Maliwan Beams are the most damaging due to the beam's capability to quickly inflict a steady stream of damage.
Tediore Beams have inferior stats compared to all others, though they do retain the Tediore Reload-Throw Gimmick, dealing more damage with more energy left in the gun. They also deal a small amount of shock damage to nearby enemies, if possible.

E-GUN behaves as a beam-barreled laser, both technically and visually although its unique barrel visually looks like a blaster barrel.
Legendary Thunderfire with Blaster barrel shoots a short-lived beam with some delay between each beam.
Hyperion Beams can spawn with Hyperion's new-style or old-style sets of materials and prefixes.
Old-style Hyperion Beams have higher damage output, slightly better rate of fire and reload speed, but lower listed accuracy.
Beam lasers are obtained randomly from any suitable loot source.
