Is it possible to make a laser by sending sunlight through an optical apparatus?
McGrew), one can still distinguish filtered sunlight from true laser light by using the 2nd-order autocorrelation function $g^2(τ)$.
For a laser: $g^2(0) = 1$. … For thermal light (e.g. sunlight): $g^2(0) = 2$
In words: While the temporal arrival time of laser photons is randomly distributed (poissonian distribution), thermal photons arrive in small bunches (Bose-Einstein …
