This one we built has a rheostat controlled variable output.

  • lmfao, its not that complicated to make it:P like seriously. i could just watch an bloody tutorial and i would be able to create a thing just like that. but seriously thats a high intensity laser. not strong to cause major damage but it could easily blind you.

  • @tomrvn666

    This video was made about 3 years ago. People weren't really putting out tutorial videos you could watch at the time. Also, the laser was weak... in the range of 5-10mW. Like seriously.

  • No protection glasses? even you built the variable control.... Your not that smart using it.... :O

  • @NoPointSketch

    By protection glasses, you mean sun-glasses (they work on this wavelength). We didn't need them. We knew the output was low.

  • Haha ok buddy. This is not complex stuff here. Rheostats in conjunction with a basic current regulating circuits allow you to control output on DPSS lasers. The video was taken with a crappy old Canon S410 camera. I would love to have the video editing skills to make a fake version of what you see here. I actually still have a video of the first one my friend and I made here: BwmnAqkT734. Or this one: 8VV7NKXjSeI .... or this one: 21n0drWI24o . I guess we faked all of them huh?

  • Check out my homepage for further experiments using laser. There are several easy to do examples to split the beam, modulate on of the two and then recombine them to produce low frequency beats. These beats should be able to induce currents into the body to transmit sound or steer muscles if used with high power lasers.

  • duamm star-warts is back

  • Not that hard to attach a rheostat to a battery assembly, We did it a lot in my PHY 111 class.

  • @FrigginSmift I know now its mostly ~1-2W of 450nm

    Dear lord please help the buyers of these powerful lasers to use safety goggles!

  • now figure out how to control the length of the beam and u will have made a light saber sir. lol

  • Ah, back in the good old days when ~20mW of 405 was the sh!t :D

  • @jayls5 -.- So many people without brains. Its at an angle because the diode didnt align with the lenses PERFECTLY so its a bit slanted. No need to hate
