According to quantum mechanics, microscopic vibrations (sound waves) in solid media are quantized. This means that vibration energy can only be exchanged in the form of so-called phonons, which have an energy which is Planck's constant h multiplied by the phonon frequency.

Phonons are important for the physics of solid-state lasers:
