The Laser Tool fires a [https://en.wikipedia.org/wiki/Laser laser] into the simulation in the direction of the cursor. If the laser intersects with an object with a [[Surface
Properties|simulated surface]], the laser will impart energy into the object, heating its surface. The rate at which this energy will be transferred depends on the laser's power and radius.
A real laser works by adding energy to a [https://en.wikipedia.org/wiki/Active_laser_medium gain medium], such as a crystal or gas. This energy, at a specific wavelength, drives [https://en.wikipedia.org/wiki/Stimulated_emission stimulated emission] in the medium and produces a narrow beam of light.
** The Magic Cold Laser will remove heat from the object's surface rather than adding heat.
** The Radius property represents the size of the spot that the laser shines on the object's surface.
Increasing the Radius of the laser will increase its Power Out.
This property represents the rate at which energy is added to the gain medium of the laser. Increasing the Power of the laser will increase its Power Out.
** Lasers are characterized based on the wavelength (i.e., color) of light that they emit.
** This property represents the gain medium of the simulated laser, and will determine the Wavelength.
▲* Power Out
* Show Beam
** A real laser is not visible until it hits an object or passes through a material that will diffract its light. When Show Beam is turned on, the laser will be artificially visible.
When a laser hits a body with a simulated surface, energy will be added to that region of the surface at a rate determined by the laser's Power Out property. This energy will be used to [[Temperature Calculation|calculate the temperature change]] of that part of the surface.
