  • Cant u just make a VIDEO and explain + show us other than showing us PICTURES of it? :/

  • waht is the power of this laser ?

  • WE WANT A TUTORIAL!!!!! damn! you rock!

  • a tip, if you can get vision damage from looking at the point from a laser higher than 5mw, you can defenitely get it from this too just by looking at the point where it's aimed at.

  • @najsbajsmedmajs Very true! That's why the only thing that ever 'sees' any of this, is my camera.

  • does it pop a ballon?

  • @UtahBraten

    If it can blast a whole in a stainless steel razor blade in one millisecond it will surely pop a balloon from across town.

  • @UtahBraten OBVIOUSLY!!!! it can burn through a bloody screwdriver

  • @UtahBraten Awww, someone's retarded.

  • Can u actually make a video of this laser in action? not justa slideshow but the laser looks AWESOME :D

    PS. i dont mean to pick holes but it looks like special effects when its a slideshow, please make a proper home video. thanks.

  • now try to eat soup with that spoon

  • Your Mom: "Why do all my utensils have tiny holes in them?"

  • Hi, where can I buy such a laser? So far, I have made just a DVD laser, with output of 200mW. So does someone know where can I buy something like THIS?

  • Nice video J. The beam looks like from an episode of StarTrek!

    I know the pulse must be very short...but can you see the beam with the naked eye?

  • Oh, yes. You can definately see it with the naked eye. However, I have only seen the output when it was carefully aimed at a distant indoor target. This was a black diffuse target. There are no second chances with this laser. One subtle reflection or glare, and you'll be walking with a cane! I have not viewed the output since it has been optimized. I let my camera be my eyes, and it has already suffered a few fried pixels in doing so. One should never see the output in person. It is dangerous!!!

  • @magx1

    I got protection-glasses for every laser...."sounds" like you dont own some for 694.

  • I do not. However, if you can still see the unfocused output scattered from a diffuse surface with safety glasses, then the glasses are no good! Throw them away.

    I shut my eyes tightly (and look away!) when the laser is being fired. At least with pulsed lasers, the danger is only momentary (and you know when it is going to take place, and can plan for it). In a way, I think the most dangerous lasers are the hand held CW ones that people buy, or that are hacked from inside other devices.

  • Actually I am handling the laser-issue just like you. The camera replaces my eyes. But I am still wearing the glasses. You never know.

    I have doubts, that the focussed beam can harm your eyes...after it has vaporized some metal.

  • Your work is also very impressive. Anyone who has not seen Anselmo's work needs to check it out.

    If you pop a shiny metal spoon, knife, or any other metal target; some of the beam is probably always reflected. I can personally testify to the fact that if the beam is not very tightly focused, a LOT of it gets reflected - the metal is like a mirror. I've observed this in some of my own experimental work. So such a laser has the potential for serious injury if not used with upmost care.

  • Dont make me blush J.

    Guess you are right. A laser is not a toy. IF I decide to sell any laser-source, I wont give it away without a matching pair of glasses!

  • Maybe you can produce HHO gas when you

    aim the laser under water to a graphite rod ?

    Please try different materials under water and let us know !

    You really have a great laser setup !

    Many thanks.

    Regards, Stefan.

  • Wow, that is a powerful laser !

    How do you build it ?

    Could you please the link to your Flickr

    page into the info box ?

    Many thanks.

    Regards, Stefan.

  • Hi,

    Thank you for your comments. Just a lot of trial and error - and a lot of help from my friends.

    Your suggestion to put the Flickr link in the information box: what a great idea! I didn't think of that before. It's done now - check the info box up top.

    Thanks for the suggestion.

  • wow that lighter flint was bright-was there anything left of it ?

  • Yes. The laser only made a small pit in the lighter flint

  • cool-i wonder what would happen if you put the flint in water and aimed the beam at the flint.....

  • Hmmm. Neat idea. Really cool.

    In fact, it would be interesting to see what happens to any target in water - really great suggestion.

    I suppose there would be some shock to the water around the target. However, I don't know if bubbles would be produced, or what would actually happen. I supppose the vaporized metal would quickly condense and float to the bottom (since soaring sparks would no longer be possible).

  • Actually, I did do the opposite (in some sense of the word): I popped some targets in a vacuum. Actually - just a jar with the air pressure greatly reduced using a water aspirator pump (a long way from a vacuum). But the resulting fire and vapor was quite an interesting display indeed - very odd in appearance. You can find photos of this on my flickr site.

  • cool i better check your flickr page out-you might just get a super heating of the water next to the target but then you might also get some potential difference and DC voltage making an electrolysis effect-maybe shoot thru a hole on one metal onto another piece of metal-that way there will be 2 electrodes separated by the water in between-im tipping there will be voltage between the two.

  • I just created a set for you. It is called Ruby Laser Shots to Target in Low Pressure Chamber. See my sets.

    There are only 4 photos. However, notice that in 2 of them, the smoke and ash are exhausted in a straight line parallel to the beam, as opposed to the typically more random direction that debris usually moves away from a target. I'm not sure why it behaves in this manner.
