| Abstract: | Using He-Ne laser,semiconductor laser,and Ar+ laser as the light sources,we observed the self-focusing phenomena of light wave at low power and the forming of spatial solitons in nematic liquid crystal. The spatial solitons with a length over five millimeters and multiple-mode spatial optical solitons were viewed. Furthermore,the forming conditions and characteristics of these solitons were also discussed. |

| Keywords: | self-trapping optical spatial solitons nematic liquid crystals |
