A laser beam is an amplified, high-intensity beam of light based on the excitation of a wave that is stationary between two mirrors, one opaque and the other translucent, resulting in a fairly powerful beam of light coming out of the translucent mirror.
Nowadays, the laser is used as a tool for reading information data, in the medical field to perform eye operations and other types of interventions, and even in the industrial field, where it is used to perform high-precision cuts. It is also used in the entertainment and show business.
