Study Notes
Laser Action Essentials
- Essential for laser action to occur: population inversion, where there are more atoms in the excited state than in the ground state
- In thermal equilibrium, there are more atoms observed in the ground state than in the excited state
- For laser action, the number of atoms in the excited state must exceed the number of atoms in the ground state
