| An abbreviation for Light Amplification by
Stimulated Emission of Radiation, the laser was discovered on Earth in
the early 20th century and came into widespread use as a weapon during
the mid 21st. Most lasers use a form of crystal or gas in which the
electrons have been raised to an excited state. Mirrors are then used
to reflect stray photons back and forth through this medium, provoking
a cascade reaction which releases a burst of light. The beam emitted
from a laser is monochromatic, coherent, and has a very high
intensity. High energy lasers are thus able to focus large amounts of
energy onto very small areas, which can result in considerable
physical damage.
Lasers remained in widespread use for some two hundred years, and
were the main armament of the Daedalus and Constitution class
starships during the early years of the Federation. By 2255 the
standard issue hand laser was capable of blasting through considerable
thickness' of rock. A larger artillery style ground cannon could
provide heavy fire - this weapon could be rigged to run from remote
power sources if required, supplying sufficient power to blast half a
continent.
Between 2255 and 2265 lasers where replaced in Starfleet service
with the much superior phasers. Today lasers are not a significant
ship-to-ship weapon, as the navigational shields of a Federation
starship are immune to this form of energy.
A Starfleet officer fires his laser pistol. This whole class of
weapon is now obsolete.
Lasers caused damage entirely by thermal effects, as shown here
when two laser beams strike a rockface.
This laser cannon was standard equipment on early Federation
Starships.
