摘要：
Breather for weak beam induced by strong beam in a strongly nonlocal nonlinear medium is investigated. Although the nonlinearity induced by the weak beam is weak enough to be negligible, the nonlinearity induced by the strong beam can balance the diffraction of the weak beam, thus the breather for weak beam comes into being. The analytical solution of the breather for weak beam is obtained. Based on the analytical solution, the evolution of the beam width is analysed, and the form as well as the direction of helix for the trajectory of the breather is systematically investigated.
