Which limitation arises when combining independent laser sources?

💡 Explanation

Achieving interference relies on coherence; thus superimposing light from independent laser beams usually gives very brief moments of high coherence. Limited temporal and spatial stability exists because truly stable interference demands matched phases, therefore, interference remains fleeting, rather than continuous.
