| Summary: | 碩士 === 國立交通大學 === 電子物理學系 === 83 === We disscuss that the laser heating effect can add the maximun
rotion angle of liquid crystal within 1.06 micron metter Nd:YAG
laser. By the measurement of the diffraction patterns induced
by the spatial sefl-phase modulation effect it can help us to
realize the temperature icrement of the sample. We found that
there was Freederiscksz transition and the threshold insity
consistent with our calculation. The number of rings that we
measured was fewer then we calculated.
