A small TEA Laser only three inches long. It is running at 120 hz rep rate using 60 hz high voltage from a neon sign transformer.

It can be easily picked up and aimed at different objects while running.

  • @TheNuclearWatermelon i think its the COD MW2 i might be wrong though

  • You have to have University or R&D lab type equipment to make these adjustments. This is NOT a home project. At first it sounds simple, but then I relized the facts stated below, and I knew I'd have to have access to such specialized calibration equipment that the monetary cost would be unbarable. So I quit the idea before even buying my first wire or metal rail. Thank goodness I didn't waste any money on something like this. It requires a skilled engineer to even build it!

  • Trick is to make the cap discharge not at one spot but along the ENTIRE length of the gap simultaneously for each pulse, for every pulse, for the whole life time of the laser.

    Even trickier is to make this laser channel be at an EXACT multiple of the wavelength, with nanometer precision!

    And lastly alligning the mirror's angle to within 1 milliradian or better (a few micro radians would be good).

    If these conditions are not ALL met, then the laser cavity simply won't lase.

  • I have to say I think you;re very foolish to HOLD it!

  • can you put electricity through it?

  • I think redesigning it could increase the efficiency a bit.

  • a finger would be enough X(

  • Because this laser produces high intensity pulses of UV light (up to about a megawatt, 500ps to 10ns depending on nitrogen pressure), these types of lasers are used to pump dye lasers, and for florescence lifetime experiments . You can get any color of the rainbow out of a dye laser. I saw many of these in the spectroscopy labs in my university. I even wrote papers, and maintained one myself..

  • i believe its mainly just a concept and second theres a lot of satisfaction having built something like this
