We compute the third harmonic field generated by Bloch-oscillating electrons in a quasioptical array of superlattices under THz irradiation. The third harmonic power transmitted oscillates with the internal electric field, with nodes associated with Bessel functions in eEd/{h_bar}{omega}. The nonlinear response of the array causes the output power to be a multivalued function of the incident laser power. The output can be optimized by adjusting the frequency of the incident pulse to match one of the Fabry-P{acute e}rot resonances in the substrate. Within the transmission-line model of the array, the maximum conversion efficiency is 0.1{percent}. {copyright} {ital 1999 American Institute of Physics.}
