One beam passes through an empty chamber and emerges unchanged.

A red beam of light emerged from it, and passed near a yellow star.

The beam burned through the back of the chair and emerged from his chest, right where his heart had been.

But no destructive beam emerged; it was pointless to make a strike that would merely wound, not kill.

A second beam of light emerged from the opposite side.

The resulting beam passes through a small aperture and emerges with the thickness of a human hair.

A narrow blue beam emerged from the tip, accompanied by a high-pitched whine.

Two of the bundles form the high beam, while the low beam emerges from the remaining set.

A beam of glorious blue light emerged from its maw and seized the Borg.

From now on, the beam would emerge in a different location every time, and he'd face hard choices.
