A Laser (Light Amplification by Stimulated Emission of Radiation) is "coherent" light. That means that all of the light is traveling in the same direction. Unlike a lightbulb, flashlight, or other "normal" light source where the light is going in all directions out from the center of the source, a Laser's light is all going in a straight line away from the source.
This is why you cannot see a laser until it hits something (dust particles in the air, for example), and also why looking directly into a Laser (yes, even one of the cheap pointer types) can cause permanent damage to your eye.
