THEL (Tactical High Energy Laser)
For years, chemical-powered lasers were seen
as the only viable alternative for
weapons-strength ray guns. The most promising
of those systems, the Tactical High Energy
Laser, successfully shot down dozens of
rockets and mortars. (this video shows it in
action.) But generating the THEL's megawatts
of laser power required hundreds of gallons
of toxic chemicals — ethylene, nitrogen
trifluoride. The weapons grew bulky (the
small-scale version was only supposed to be
kept in a mere right cargo containers, each
40 feet long). Worse, after a few shots, the
lasers would have to be resupplied with a
fresh batch of reactants. The logistics of
hauling those toxins either through the air
or across a battlefield made generals shiver.
So, ultimately, interest swung back to solid
state systems, like Yamamoto's, and, to a
lesser extent, free electron lasers.
