How to Use Light to Cut Stone

Roll the laser into position. Most laser cutting systems are large and computer controlled. Use the computer's targeting system to point the laser at the target location of the rock. Some lasers also use lenses to focus the laser light to increase the laser beam's power. If a lens is needed, position it between the rock and laser head. The objective is to focus the laser beam so that its hottest point is at the face of the rock.

Connect the laser to the laser power supply. Startup the power supply and begin increasing the power level to the level needed to fire the laser. Also, start the laser cooling system. Different types of lasers generate different amounts of heat. A cooling system is used to remove the excess heat and protect the laser. Once the needed power level is reached, trigger the laser.

Begin hitting the rock with a low volume of water as the laser is fired. The water is used to remove the excess heat generated by the laser cutting action, and any loose material in the work area.

Hit the rock with the laser beam and slowly cut sections out of the rock. The speed of the laser cutting action depends on the size and power of the laser. Small lasers are good for cutting rock. Large lasers have the ability to melt or vaporize rocks. Once the rock has been cut as needed, shut off the laser and allow it to cool down.
