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
Test your knowledge of laser physics and thermal equilibrium with this quiz. Explore the relationship between the number of atoms in different energy levels and their significance for laser action.
