title: Effects of magnetic fields on four-wave mixing processes in atomic vapors.
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 omega(1) + omega(2) + omega(3) ? omega(4) in fields of up to 50 kG. Magnetic tuning of the resonances of the third-order nonlinear susceptibility X((3)) was used to modify the dependence of the sum-frequency output power on the generated wavelength.
