摘要:
We present the results of a detailed experimental study of the self‐focusing of a low intensity cw laser in its passage through a nematic liquid‐crystal film. The results are in quantitative agreement with our theory of optically induced birefringence as a function of geometry, thickness, and intensity. We have also quantitatively measured the relative contribution from thermal lensing effect.
