Few-femtosecond phase-sensitive detection of infrared electric fields with a third-order nonlinearity
Abstract Measuring an electric field waveform beyond radio frequencies is often accomplished via a second-order nonlinear interaction with a laser pulse shorter than half of the field’s oscillation period. However, synthesizing such a gate pulse is extremely challenging when sampling mid- (MIR) and...
