What is the principle that the laser produces great heat? If you contact the laser equipment, if you accidentally hit the laser on the human body, will you break the body instantly?
For the sake of simplicity, we can as shown in Figure 1, the order can imagine some around the nuclear track, the farther distance away from the nucleus of the orbital energy is higher. In addition, the number of electrons in different orbits can hold up is different,
The neutron proton has a positive charge, is not charged atoms with peripheral. The negatively charged electrons, around the nucleus. Interestingly, electrons in an atom energy is not arbitrary. Quantum mechanics description of the microscopic world tells us that these electrons will in some fixed order "to" different energy level corresponding to the electronic energy is not the same.
Understand the laser generating principle, we must understand the material structure, and light absorption and radiation and the principle of matter consist of atoms. Figure 1 is a diagram of a carbon atom. The atomic center is the nucleus, composed of protons and neutrons
