This project is a great fun as you can make a high power laser out of your DVD burner while sitting at home. The laser has a peak output of 225mW and is visible red at about 650nm. This laser can perform all the functions performed by Pulsar 150-wicked laser like light matches, pop balloons and cut electric tapes etc.

Moreover, this laser will only cost you one third of cost of Pulsar 150. to learn how to make one just click here.
