 You
might just see lasers
in science fiction films,
but in fact they surround
us in our everyday lives.
Did you know that there
are lasers in CD players,
pointing devices, supermarket
scanners, and all kinds
of medical instruments?
And lasers are not as
complicated as you might
think. Johnny Alonso spoke
with researcher Gary Fleming
at NASA Langley Research
Center to find out how
a laser works.
