Stimulated Absorption
When a photon of light having energy E2 – E1 = hυ is incident on an atom in the ground state, the atom in the ground state E1 may absorb the photon and jump to higher energy state E2. This process is called stimulated absorption or induced absorption. This is called so because the incident photon has stimulated the atom to absorb the energy.
