High power laser pointer burn

A powerful laser pointer is a very concentrated beam of light that can burn things because the light energy is absorbed by some objects and converted into heat.

The burning capacity of a small laser pointer depends on several factors.

Laser Output Power: Higher power laser beams make things easier and faster.

Laser Beamwidth: A narrow laser beam will always burn more than a wide laser beam.

Object Color: Dark objects usually absorb more light energy, making them easier to burn than bright objects that may not absorb light energy.

Immobility: The laser beam that moves an object does not have enough time to absorb light energy. The tip of the laser beam still needs to hold the object for a few seconds to burn it.
