Analytic solutions of the optical Bloch equations - ScienceDirect
Webthe optical Bloch equations are obtained. The Bloch equations are supposed to describe a two-level system with spontaneous relaxation from state 2i to 1i . This is not yet included in the derivation and requires a modification of equation 4.7 in such a way that in absence of a laser field the population ρ22 and thus c2 vanishes. WebMay 1, 2024 · The propagation of the ultrashort hyper-Gaussian pulses of different orders (Eq. (7)) in two-photon resonance with the three-level system ω = ω 20 ∕ 2 = ω 0 are simulated by solving numerically the full-wave Maxwell’s equations (1) and the three-level optical Bloch equations (3) [35]. Web2.1.2 Optical Bloch equations for a four-level system This section provides the explicit form of the Hamiltonian of the laser light and ion which is derived in appendix B.
