本實驗首先合成三種高對稱性的恩焜如1,4-anthraquinone,
6,13-pentacenequinone以及6,15-hexacenequinone,進而測量此類化合物
的非線性穿透率,以觀察它們的雙光子吸收及可能的光物理途徑.同時,我
們使用Z軸掃描方法,測量這些化合物及苯環上有取代基的9,10-
anthraquinone等的三次非線性吸收及折射等現象.以上的非線性測量使用
的激發光源以石榴石雷射的倍頻光束(532 ns)為主,其脈衝時寬為8 ns.另
外對Z軸掃描的基本原理和計算方法,以及用來推算三次非線性係數的數值
分析方法,在文中有詳細的說明.

The linear para acenequinone of 1,4-anthraquinone,
6,13-pentacenequinone and 6,15-hexacenequinone have been
synthesized in this research. The feasible two-photon absorption
has been observed with the nonlinear transmission measurement of
these compounds. The third-order absorption and refraction
properties of these linear acenequinone and some substituted
compounds of 9,10-anthraquinone have been investigated with the
z-scan method. The Nd:YAG laser with 532 nm wavelength and 8 ns
pulsewidth has been used for all the measurements above.
Forthermore, the basic principles of the z-scan technique and
the numerical calculatiuon that we nave applied in this thesis
have been explained in further detail.
