If a photon hits an atom in a low energy state, the atom can absorb the photon’s energy. This boosts the atom to a higher, excited energy state. The energy of the incoming photon must exactly match the energy gap between the two states. Stimulated Emission
The book starts by establishing the wave nature of light using Maxwell’s equations. It covers:
This text separates itself from others through several innovative features:
Silfvast famously introduces lasers by breaking them down into three fundamental components:
The lower laser level is the ground state. These systems require intense pumping because more than half of the entire ground-state population must be excited to achieve inversion (e.g., Ruby lasers).
