I was looking around in my documents and ran into a video I took a while back of an attempt to burn through a Rubik's Cube with my laser.

I was planning on burning through the Rubik's Cube, lighting a match on the other side once it is through the Rubik's Cube. It didn't go the way I had planned, probably because I did not have the laser focused properly. After a minute or so I turned it off to avoid overheating the laser.

Link to video on Photobucket, because I don't have a YouTube account. The video itself isn't really exciting, but you do get to see a Rubik's Cube smoke for a while.

Here's the damage done to the cube:

Perhaps I'll make another attempt at completely burning through the cube another time...

If anyone was wondering, the laser in my video is a 1.1W blue laser.

Obligatory warning:
Now please don't go run and buy a powerful laser after seeing this. Powerful lasers can be very (and I mean VERY) dangerous and should be handled like a weapon would be. This experiment was done in a controlled environment (at least as much as possible), proper safety glasses (OD5+) and laser safety was observed. I have this laser locked up as I would a gun. Never point a laser at another moving vehicle/aircraft or at another person or living thing.

Here's the pain a laser of this power could inflict:

Why were you trying to burn through a cube? Actually, a powerful enough laser would make the Octagonal Barrel a lot easier to create... but then I firmly believe that if a laser is powerful enough, at some point it will inherit the properties of a lightsaber.

Isn't a 1.1W blue laser powerful to permanently damage your retina from the reflection off a white wall/ paper?

I'm not sure the extent of damage it will cause, but I certainly would not dare to look at anything in that room without the safety glasses. This was actually why I took this video.

At the time of the video, I didn't have a beam dump but I've since acquired a beam dump to absorb some of the output on the other end.

I wanted to test my laser out, but didn't have any black jewel cases to cut through, so I figured a cube I had for parts will do :lol:

You do? You think a sufficiently intense beam of coherent light can stop abruptly after about three feet and physically block another beam from passing through it? Lightsabers are awesome, I agree, but come on. They're absurd.

Ah, but lightsabers aren't even supposed to be lasers; they're plasma, inside force fields. Still impossible for us to make, but slightly less far-fetched than coherent lasers.

Ben, You have a 1.1 watt 445 nm laser? I have two of them, I made them myself. Have you heard of Laser Pointer Forums? BTW, why would you do that to a Rubik's Cube?

If you want a "cool" way to cut something, try a waterjet :shock:

we are overthinking this......


but while we are... plasma can be affected by magnets so hypothetically it could be used to contain the plasma

I meant it would cut through stuff instantly, not suddenly become a light beam with finite length. Note to self: never mention physics on a nerd-oriented forum :)

The use of force here has never been more literal.
