Quantum Optics : Including Noise Reduction Trapped Ions Quantum Trajectories and Decoherence Quantum Optics gives a very broad coverage of basic laser related phenomena that allow scientists and engineers to carry out research in quantum optics and laser physics. It covers the quantization of the electromagnetic field quantum theory of coherence atom field interaction models resonance fluorescence quantum theory of damping laser theory using both the master equation and the Langevin approach the correlated emission laser input output theory with application in nonlinear optics quantum trajectories atom optics quantum non demolition measurements and generation of non classsical vibrational states of ions in a Paul trap. These topics are presented in a unified and didactic manner. The presentation of the book is clear and pedagogical; it balances the theoretical aspects of the optical phenomena with recent relevant experiments
