How does a laser cut diamond?

I know (at least I think) that there are only two things that can cut diamond: other diamonds and lasers. I understand how other diamonds can cut it, but what I don't get is the concept of a laser (basically light, right?) can cut the hardest material on Earth. What properties of a laser enables it to cut something as hard as diamond? The concept of light cutting something seems impossible to me.|||A laser is concentrated light, light is energy, so the lazer is concentrated beam of energy. It doesn't so much cut the diamond as volatalize it, gasify the carbon from the intense heat of the concentrated energy beam.|||..is the heat intensity of the light..
