Implied:
* Energy weapons

Similar:
* Stream projectors

Contrast:
* LASER bolts - LASERs should be beams, but these are not, and therefore not part of beam weapons.

The fanciest among these are electrolasers or weapons that produce similar effect, outwardly appearing as lightning guns but the kind that produce straight firing electron bolt with no arcing.

Energy beams:
* Laser
* Electrolaser

Particle beams:
* Plasma

Does NOT include any sort of mass drivers or accelerators that propel physical objects to high speeds using various methods from small controlled explosions to magnetic rails.

Does NOT include weapons that are beam weapons only in name, such as lasers in Star Wars (see laser bolts tag for that). That is, beams connect from start point to the end point simultaneously, not travel the distance over time like a bolt does.
