研究調制雙偏振摻釹釔鋁石榴石(Nd:YAG)雷射的輸出特性與動態行為，雙偏振雷射存在三種鬆弛振盪頻率，其中較高頻率對應典型的鬆弛震盪頻率，而其他負責正交偏振模的反相動力學。在低泵源功率下的反向模態會消失。當調制頻率接近典型的鬆弛震盪頻率時，觀察到倍週期路徑進入混沌，其中兩個是負責正交偏振模的反相動力學。兩個正交偏振輸出強度的平均震盪頻率會在調制頻率附近，與此相反，當調制頻率接近反相模態的頻率時，兩個偏振的平均頻率是不同的。此外，兩個正交偏振強度之間的同步藉由CPR方法進行了分析和討論。

Characteristics and dynamic behaviors of the bipolarized Nd:YAG laser using pump modulation were studied. Three relaxation oscillation frequencies exist in the bipolarized lasing regime, in which the highest frequency corresponds to the typical relaxation oscillation frequency and the other are responsible for the antiphase dynamics of orthogonally polarization modes. The antiphase mode disappeared as the low pump power. When the modulation frequency approached to the typical relaxation oscillation frequency, the period-doubling route to chaos was observed. The average oscillating frequencies of the output intensity in both orthogonal polarizations were near the modulation frequency. On the contrary, the average frequencies in two polarizations would be different when the modulation frequency approached to the frequency of the antiphase mode. Moreover, the synchronization of the intensities between two orthogonal polarizations were analyzed and discussed by Correlation between Probabilities of Recurrence method.
