The effects of laser and how it functions
Laser, simply put, are devices that use light and heat energy and emit some heat for it to be used on certain skin types and other purposes. ‘Laser’ is a short form of ‘light amplification by stimulated emission of radiation. This change of energy is what causes most laser operations to take place all over the globe and this is how a typical laser actually works. For example, for laser cutting, special lasers are used and what makes them different from a simple light emitting object is basically, because of the ‘tight spot’ that the light is focussed on and how it just emits light on that very spot and makes heat emission and therefore, the operation easier.
