Top 5 Facts About Lasers


[Music]
it’s time to set phasers from stun to
inform welcome to watchmojo.com ting
down the five most vaporizing facts
about lasers that’s light wave
amplification by stimulated emission of
radiation for those of you who hate
acronyms not a laser there’s a little
light bulb with blanks what’s with him
laser envy number five laser light shows
can ruin your camera we’ve all been
tempted to pull out our phones at a
concert and record our favorite song
watch out because you’re actually
running the risk of destroying it your
camera not the song videos of camera
kills have popped up online showing the
moment light meets lens and the results
are fatal this is because when
concentrated beams of light make contact
with a camera sensor it can become
overexposed burning it out instantly
let’s just take a moment to mourn the
loss of all those cameras that have
perished at EDM concerts number four
laser tag was developed by the military
nothing says birthday party like a
sporting game of laser tag it’s fun it’s
competitive and it’s a great way to gain
much-needed experience for shooting down
real-life enemy targets welcome to the
war okay first let’s just try to create
a dialogue that’s right back in the
1970s the United States military
developed laser tag as a means of
training its troops the game was
originally titled multiple integrated
laser engagement system or miles for
short and a far more advanced version is
even used to this day Dakota it’s laser
way but number three sci-fi weapons
already exist are those shirts with
laser beams attached to their heads when
we think of laser beams we think of
those nifty rifles and ray guns from
sci-fi classics but the United States
military is well on its way to
developing something quite similar DARPA
announced that they were well on their
way to developing a laser weapon of
unprecedented power known as hell ads
the weapon is a fighter jet mounted
weapon that can produce a 75 kilowatt
beam of laser nasty
though this death ray can’t be seen and
we don’t hear the ubiquitous pew pew
it’ll be devastating nonetheless looks
like we may be well on our way to
piloting X wings after all number two
lasers can reach unimaginable
temperatures it can project a spot on
the moon or at closer range
cut through solid metal I will show you
scientists from Imperial College London
recently proposed a method whereby
lasers could heat materials to over 27
million degrees Fahrenheit that’s hotter
than the center of the Sun this
development could help scientists
replicate the much needed energy given
by the Sun allowing for a cleaner method
of energy production conversely it’s
also quite possible to make lasers that
can cool down a material researchers at
the University of Washington discovered
this breakthrough by using a combination
of delicate infrared laser lights and
crystals suspended in water though there
are too many practical uses for such a
thing you could theoretically build your
supervillain arsenal around it you
expect me to talk number one lasers have
many many uses lasers Church laser
sharks the previous entries may suggest
otherwise but lasers aren’t just for
destruction yes it may go without saying
but there’s a buttload of applications
for them including engraving printing
eye correction and hair removal but one
particularly novel use would be that of
light detection and ranging so-called
lidar devices are able to send a series
of light pulses that scan environments
and produce a detailed mapping of their
structure as is the case for most laser
applications these readings are accurate
to a tee and can assist builders and
geologists far more than previous means
so whether they’re harmful helpful or
otherwise lasers have become a staple in
our human ecosystem arm the laser so are
you wanting to hit up the old laser
Quest now oh shut it and do you think
we’ll see massive weaponized lasers in
our lifetime meaning me stop humping the
laser until next time for more hotter
than the Sun top tens and balding a
stigmatic top fives be sure to subscribe
to watchmojo.com you just saved my life
didn’t you thank me later let’s keep
moving these little bastards are
everywhere
