Hyperspace laser

Tenn felt sweat dripping down his neck, under that blasted helmet. He looked at the timer: 00:58:57.

 He pulled the lever.

 It would take a second or so for the tributary beams to coalesce. He wanted to look away from the monitor, but he couldn't.

The superlaser beam lanced from the focusing point above the dish.  The image of Alderaan on the screen was struck by the green ray.  It took no more than an instant. Tenn knew that the beam's total destructive power was much bigger than matter-energy conversions limited to realspace. At full charge, the hyper-matter reactor provided a superluminal "boost" that caused much of the planet's mass to be shifted immediately into hyperspace. As a result, Alderaan exploded into a fiery ball of eye-smiting light almost instantaneously, and a planar ring of energy reflux-the "shadow" of a hyperspatial ripple-spread rapidly outward.

 The timer read: 00:59:10.

 So little time. So much damage. It was incredible.
