Can You Trap A Laser beam In 3 mirrors in the form of a triangle?

Answer 1

Hi...

Only if the laser beam was sent through one of the mirrors are if they were totally synchronized...

Or even... If the triangle was inscribed in a 1,000 miles diameter circle, to let you send the beam, and the replace (automatically) the laser beam sender by the third mirror in the triangle...

But it will always loose some energy... and it won't be really trapped!

But I usually don't work with lasers... so... who am I to answer!? ;)

Have a nice day!

Answer 2

You couldn't keep a beam bouncing around for any length of time if that is what you mean. I read an article on this years ago. If you had telescope mirror grade reflection surface on the inside of a 1 foot diameter sphere and could somehow introduce a flash of light inside, how long would the light last? The reflection efficiency is over 97%, but use 98% just to be generous. The answer is: The light would become undetectable in less than 1 second. Give the speed of light, compute the number of reflections per second and determine how much light would be left at the end of 1 second. So if you could introduce a laser beam into a setup of 3 mirrors, the beam would last less than 1 second when the laser was removed.

Answer 3

No. The problem is that in order to keep the beam reflecting through the three mirrors, the beam needs to pass back through its own point of origin. That is, the laser device itself is in the way of the beam continuing to reflect through all three mirrors. Even if it were possible to trap the beam in the way you've suggested (which would require moving the laser device at a speed faster than that of light), the laser beam would eventually degrade and appear to vanish; lasers are focused, but not infinitely so.

Answer 4

yes
if u put the laser beam`s source in herizontal plane and the three mirrors in the vertical plane away from each other any distance u like first make the beam fall on the first mirror then adjust that mirror so that the beam fall onto the other mirror finally adjust the position of the third one so that the beam falls onto the first one in the same point the beam first fall on the first so it wiil reflect on it self to infinity
lol

Answer 5

In reality, no.

Hypothetically, it could be done, but there would be many constraints. No energy can be lost by the beam, which means it must be a perfect beam and must hit perfect mirrors every time, and nothing that can absorb light or heat can be present anywhere.

Answer 6

Certainly. Such a device is used as a rotational accelerometer; you send laser beams around in both directions, and measure the phase difference to detect whether the assembly is rotating.

Answer 7

Nice idea.
But light is lost during reflection, since the mirror absorbs some percentage of it. So it would soon(a few nanoseconds) die out.

Answer 8

I read that it creates a Hologram. I read about it in some book years ago. I think there might more involved with the process. I no longer have that book, or I would have looked it up for you. Sorry.-----Is that what you are trying to do?
Good Luck

Answer 9

nope
The laser has a starting point and to make a closed loop of light would make it pass through the starting point .
You can make it a really tight spiral

Answer 10

Yes.

But do not recall when this ability is available to general public so
will refrain from further comment.
