Description

We have constructed an instrument for observing the second harmonic generation (SHG) in the soft x‐ray region. The two beams are focused on the GaAs thin film, and the scattered beam corresponding to the SHG signal is detected by a photomultiplier tube (PMT). For detecting the small signal of the SHG, we have developed a novel modulation technique with a piezo actuator and a digital lock‐in amplifier. The result of the experiment is almost consistent with the assumption that the SHG has been detected in our experiment.
