研究目的
To derive a set of analytical phase shift formulas for a plane-parallel electro-optical crystal plate at arbitrary incidence angle and azimuth angle, enabling the analysis of phase shift induced by an electro-optical crystal with an arbitrary incident direction.
研究成果
The derived phase shift formulas enable the analysis of phase shift in electro-optical crystals with an arbitrary incident direction. The phase shift in a lithium niobate crystal is influenced by both the incidence angle and the azimuth angle when an external electric field is applied. The experimental results validate the correctness of the derived formulas, showing good agreement with theoretical predictions.
研究不足
The study focuses on the phase shift in electro-optical crystals with an arbitrary incident direction, but the practical applications may be limited by the precision of crystal alignment and the stability of the experimental setup.
