SUMMARY
The discussion centers on the concept of phase in relation to laser states, specifically addressing the absence of a phase reference leading to a Poissonian mixture of number states. It clarifies that a quantum state represented as ##|\psi\rangle= c_0|0\rangle+c_1 |1 \rangle +c_2|2\rangle \ldots## is a superposition of number states. When the coefficients ##|c_i|^2## follow a Poisson distribution and the ratio ##c_{n+1}/c_n \sim \exp(i\phi)##, the state is identified as a coherent state with phase ##\phi##, closely resembling classical states in quantum mechanics.
