It is show that the initial power and the incident angle of the beam are important factors of formation and stable propagation of soliton . when the initial power matches with the beam width, a balance of diffraction and nonlinearity effects in propagation will be maintained and therefore the stable nonlinear lattice soliton comes into being 研究發(fā)現(xiàn):光束的初始功率和入射角度是格子孤子形成和穩(wěn)定傳輸?shù)闹匾蛩?當光束的初始功率與光束寬度滿足一定條件時,可以維持傳輸過程中衍射和非線性效應的精確平衡,從而形成穩(wěn)定的三階非線性格子孤子。
