Step 1: Prepare your Lasers.
We removed the mounting brackets and prepared them with matching power supplies to be placed on the tree. If you don't have access to continuous operation lasers you can use a regular laser pointers by taping the button so it stays on. Your battery will die eventually, but you'll have a temporary solution to create your own display. Green laser pointers can be purchased from both Laserglow.com and Novalasers.com.
Step 2: Attach Diffraction Gratings to your Lasers.
Step 3: Attach Lasers to the Christmas Tree.
We spread out the lasers to have contrasting colours between the red and the green lasers, and we also tried to have a variety of Diffraction Gratings to create a more dynamic display.
Step 4: Adjust the Lasers
Step 5: Add your Star.
Step 6: Add some Fog or Smoke.
Keep in mind that your tree will look best when all the lights are completely off, so if you wish to add ornaments be sure to showcase the ones that reflect laser beams and are visible in the dark. Adding smoke or fog now will reveal all beams projecting from the tree and truly make your Laser Tree come to life. Fog can be purchased from Novalasers.com.
