Theory of dressed-state lasers. II. Phase diffusion and squeezing
Jakub Zakrzewski, Maciej Lewenstein, THOMAS W. MOSSBERG · Physical Review A · 1991
We present a detailed theory of the quantum-statistical properties of dressed-state lasers, i.e., lasers that operate due to the gain on an inverted transition between dressed states of a coupled atom-field system. With the help of quantum Langevin equations, we calculate squeezing spectra of such lasers. One-photon dressed-state lasers exhibit large squeezing due to antiresonant transitions between dressed states that lead to Bloch-Siegert-type shift effects. Two-photon dressed-state lasers may also generate squeezed light.
