He started working with lasers while he was DJing in clubs in Denver and Boulder. He uses two lasers, both argon gas lasers. If you take those 100 watts and focus them into as narrow a beam as the laser, you'd blow a hole though a wall.
Lasers send electricity through a tube of gas.
When the gas is charged, it emits a certain colored light. The light is focused onto two mirrors through fiber-optic cables, one mirror moving horizontally and the other moving vertically. The mirrors are controlled by a computer, which is programmed to move the mirrors to draw certain shapes and patterns and even logos. DeHerrera plans to buy a mixed-gas, or whitelight, laser. A prism separates the individual colors.
