Abstract: The present invention provides an electrooptic Q-switch element made of a single crystal. The invention includes a langasite (LGS) single crystal and a reflection element located on one side of the langasite crystal along the light propagation direction. A light beam penetrates the LGS crystal along the main optical axis, is reflected by the reflection element, and passes through the LGS crystal again, so that the rotation angle of the polarization plane of the light originating from the optical activity is zero degrees. One advantage of the electrooptic Q-switch is its low, adjustable, high stable half-wave voltage. The invention can overcome the problems associated with current commercial Q-switches, such as high, non-adjustable, low stable half-wave voltage and great half-wave voltage variation with temperature.
