要約(日本語): In this work, a novel approach of measuring the electric field is proposed by combining a second harmonic generation (SHG) technique with an electro-optic effect in nonlinear crystals. A diode laser was used with a nonlinear, electro-optic crystal and the feasibility of the technique for the measurement of slow and fast electrical fields was studied. The experimental measurements combined with theoretical estimates show that even though the temperature control of the nonlinear crystal is a critical requirement, the SHG technique in electro-optic crystals, such as LiNbO₃, KTiOPO₄, can be effectively used for electric field measurements with a wide dynamic range of the order of few kV/cm.
