A view of the second harmonic generation (SHG) set-up at TPCI.
SHG analysis includes è-scans in pp and sp polarization in which the SHG intensity is recorded as a function of the angle between the sample poled surface and the probe beam. ø-scan measurements in p and s polarization can be also performed, where the polarization of the incident beam is varied for a fixed sample position è (ISM, Bordeaux).
