Comparison of semi-classical and quantum theories for a single-mode laser
L. Allen
The dependence on cavity Q of the intensity of a single-mode laser above threshold is examined for the quantum and semi-classical theories due to Scully and Lamb (1967), and Stenholm and Lamb, respectively. The two theories predict different functional dependencies, but comparison with previously published results show that both theories are satisfied for the small relative excitations possible in a He-Ne laser.
