Nonlinear responses of superconductors to intense terahertz radiation has been an active research frontier. Using pump-terahertz probe spectroscopy, we investigate the c-axis nonlinear optical response a high-temperature superconducting cuprate. After excitation by single-cycle pump pulse, reflectivity pulse oscillates as pump-probe delay is varied. Interestingly, oscillatory central frequency scales linearly with frequency, fact widely overlooked in experiments. By theoretically solving...
