WebA general study of a two-level system. Consider a physical system whose state space is two-dimensional. (Usually this is an approximation). Assume that if the system is not externally perturbed, its Hamiltonian is H 0. (An example is a spin ½ particle in a magnetic field B ≈ B 0 k.Here H 0 = ω 0 S z, ω 0 = -γB 0.). The eigenstate of H 0 are Φ 1 > and Φ 2 >, and the …
WebConsider a four level laser system Level 1 is the ground level and levels 2;3;and 4 are excited levels of the system. Atoms from the level 1 are excited by a pump to level 4, from which the atoms decay very rapidly through some nonradiative transition to level 3. Level 3 is a metastable level having a long lifetime.
