I Two-Level Atom Driven by Two Lasers?

    Hey all,

    I am looking for a reference that derives the optical Bloch equations for a two-level system driven by two near-detuned monochromatic radiation sources. Specifically, I am looking to substantiate a result I derived by following the same procedure as for a two-level atom driven by a single radiation source: $$\frac{d\vec{R}}{dt} = \vec{R} \times \vec{W}$$ where $$\vec{W} = [\Omega_1 + \Omega_2 \mathrm{cos}(\delta_2 - \delta_1),\Omega_{2}\mathrm{sin}(\delta_2 - \delta_1),\hbar \delta_1]^{\mathrm{T}}$$ in which $$\hbar \Omega_n = e \langle \vec{x} \cdot \vec{E_{n}} \rangle$$ and ##\delta_n## is the detuning of the n-th laser and ##\vec{E_n}## is the amplitude and polarization of the beam.

    Edit: I don't need the spontaneous emission contribution, because I'm putting this in a Monte Carlo simulation where I handle spontaneous emission as a random process for each atom.

    Thanks in advance!

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
