1. Chang, Wei-Jin. Measurement of Two-photon absorption cross section of diacrylate using Z-scan technique.

Degree: Master, Electro-Optical Engineering, 2017, NSYSU

Diacrylate mesogen is a kind of main chain liquid crystal polymers which has good photosensitive property, can be polymerized using UV-light and heat. It can be used for the holographic recording as the photonsensitive material. In past research, we used long wavelength laser beam to illuminate diacrylate mesogens RM82 and RM257, and found that they were polymerized. It was also found that the laser interference fringes may be recorded in the liquid crystal samples. It was thought that the polymerization of the diacrylates was caused by two photon absorption. However, the evidence that can be used for supporting the inference has not been found. Two-photon absorption is that the electron absorbs two photons in a very short period of time and transitions to the excited state, and the energy of two photons is equal to the energy difference between two energy state. In this study, we used Z-scan technique to verify the two-photon absorption property of diacrylate mesogen. Z-scan is a simple yet and highly sensitive measurement technology, which can be used to measure nonlinear optical properties. Using the Open aperture Z-scan, we obtained the two photon absorption cross-section of the diacrylate successfully, and verify that diacrylate mesogen is a good two-photon absorption material.
