Abstract
We have observed the effects of magnetic fields on four-wave mixing processes in atomic vapors. We have studied coherent vacuum-ultraviolet generation in Sr vapor via the process ω1 + ω2 + ω3 → ω4 in fields of up to 50 kG. Magnetic tuning of the resonances of the third-order nonlinear susceptibility χ(3) was used to modify the dependence of the sum-frequency output power on the generated wavelength.
