Abstract
The quadrupole-allowed three-wave mixing (omega(1) + omega(2) = omega( 3)) in an anisotropic electron gas is calculated using the Boltzmann e quation. The nonlinear polarizabilities are evaluated within a two-ban d model suitable for description of the optical response of noble meta ls at frequencies below the d-band transitions. For the infrared-visib le (omega(1) much greater than omega(2)) sum-frequency generation the effects of the lattice structure are found to be much stronger than th ose for the degenerate (omega(1) = omega(2)) second-harmonic generatio n.
