在本文中，量測經900℃氣氛處理鈦酸鋇單晶與經1000℃氣氛處理鈦酸鋇單晶的光學性質、光折變性質以及導電率特性。經過實驗量測後，得到以下的結論：
1.從雙波混合能量增益係數實驗、黑暗衰減實驗、光致衰減實驗，可以得到經900℃氣氛處理鈦酸鋇單晶與經1000℃氣氛處理鈦酸鋇單晶的各項光折變特性以及行為所符合的能階模型和影響光折變現象的主要因素。
2.利用Thermodynamic Defect Model理論來解釋吸收光譜、雙波混合、黑暗衰減、光致衰減的實驗結果，並且藉由此理論瞭解到，不同氧偏壓的氣氛處理在影響鈦酸鋇單晶光學及光折變性質所扮演的角色。
3.從實驗結果中發現，不同溫度下氣氛處理對鈦酸鋇單晶光學及光折變性質的影響。
4.從導電率量測實驗，發展出利用外加電場的方式來量測鈦酸鋇晶體導電率性質技術，但尚未完全成熟。同時，在實驗中發現的種種疑點，為向另一個未知研究領域踏出的第一步。
