Rapid E-FISH measurements using a laser optical loop

Year: 2025

Type: article

Abstract: Rapid electric field–induced second harmonic generation measurements are performed using a laser optical loop approach, which facilitates the use of each single laser shot several times. From a single laser shot, E-FISH signals at multiple points in the time domain are generated and recorded as a single waveform. It is also demonstrated experimentally that the polarization-sensitive nature of E-FISH allows to tailor the E-FISH response sensitivity within the pulse train traveling in the optical loop to optimize the measured signal waveform for a given electric field profile while avoiding the saturation of the detector and extending the dynamics range of the measurements.
