If a coherent light pulse is input into an optical cavity with a high Q-factor, which consequence follows for photons within the cavity?

💡 Explanation

The photons exhibit increased bunching because the coherent input enhances stimulated emission inside the cavity, causing photons to be emitted in correlated pairs. Therefore, photon bunching becomes more probable, rather than the alternative outcomes of suppressed emission or reduced entanglement which are not directly driven by coherent input.
