Fiftyyears ago this Sunday, Theodore Maiman and his fellow scientists atHughes Research Laboratory shined a high-power flash lamp on a rubyrod, triggering a beam of coherentlight: the first laser.
The intensity of the coherentlight builds up very rapidly.

The results show that the atom lasers induced by light field in Fock state, coherent state, and squeezing coherent state are always anti-bunching, the nth-order coherent, and bunching, respectively.
