摘要
文章研究了单束和双束连续Ar^+激光照射到垂面排列的丝状液晶薄膜所产生的光调制和光放大效应。利用球面波激光束通过液晶膜所产生的空间自相位调制效应能实现光—光调制放大作用。对5CB液晶所作的理论分析与实验结果很好地符合。
We have studied optical modulation and optical amplification with a single beam and two beams CW Ar^+ Laser in homeotropically aligned nematic liquid-crystal films. Using the spatial self-phase modulation of the Laser beam with the spherical wave travcrsing the liquid-crystal films, we can realize opto-optical modulated amplification. The theoretical analysis is in quantitative, agreement with the experimental results for 5CB liquid_mcrystals.
