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 PropertiesSimulation|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.
* Radius
** The Radius property represents the size of the spot that the laser shines on the object's surface. IncreasingRadius, theTotal RadiusPower, ofand thePower laserper willArea increaseare its[[Locked PowerProperties|locked Outproperties]].
* Total Power
** ThisThe propertyPower Out of the laser represents the rate at which energy iswill be added to the gainobject medium ofthat the laser hits. IncreasingRadius, theTotal Power, ofand thePower laserper willArea increaseare its[[Locked PowerProperties|locked Outproperties]].
* Power Outper Area
** The Power per Area represents the power per area of the object's surface. Radius, Total Power, and Power per Area are [[Locked Properties|locked properties]].
* Auto Radius
** When the Auto Radius toggle is on, the radius of the laser will be set automatically based on the radius of the target object.
* Wavelength
** Lasers are characterized based on the wavelength (i.e., color) of light that they emit.
** Medium
*** This property represents the gain medium of the simulated laser, and will determine the Wavelength.
* Power Out
** The Power Out of the laser represents the rate at which energy will be added to the object that the laser hits. The value of the Power Out is automatically calculated by Universe Sandbox based on the laser's Radius and Power.
* 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.
