Laddering Down A hypothetical technique for overcoming a terminal phase missile defense.
Successive salvos of salvage-fused RVs attack. The detonations of one salvo
disable local ABM abilities so that following salvos are able to approach the
target more closely before being, in turn, intercepted. Eventually, by repeating
the process, the target is reached and destroyed.

Large Optics The technology of constructing and employing mirrors over 1 m aperture to direct
and control high power beam weapons/systems with large coverage, or to
provide high resolution or high sensitivity for detection and/or imaging.
LASA Large Aperture Seismic Array.
Lasant A material that can be stimulated to produce laser light. Many materials can be
used as lasants; these can be in solid, liquid, or gaseous form (consisting of
molecules including excimers or atoms) or in the form of plasma (consisting of
ions and electrons). Lasant materials useful in high energy lasers include carbon
dioxide, carbon monoxide, deuterium fluoride, hydrogen fluoride, iodine, xenon
chloride, krypton fluoride, and selenium, to mention but a few.
LASE LIDAR Acquisition and Sizing Experiment.
Laser An active electron device that converts input power into a very narrow, intense
beam of coherent visible or infrared light; the input power excites the atoms of an
