| Abstract: | The device for crystal electro-optical modulation experiment was technically modified to make the optical path adjustment easily operated.The technique collimated the incident and reflected light beams by adjusting the light source and crystallographic orientation and making use of two small diaphragms in the optical path to confirm that the incident light was along the optical axis.Detailed method was given on how to adjust the optical path.It was found that the measurements with this device were more accu... |
