| 中文摘要 | the spatiotemporal evolutions of ultrashort pulses in two dimensions are investigated numerically by solving the coupled maxwell-bloch equations without invoking the slowly varying envelope approximation and rotating-wave approximation. for an on-axis 2n pi sech pulse, local delay makes the temporal split 2 pi sech pulses crescent-shaped in the transverse distribution. due to the transverse effect, the temporal split 2 pi sech pulses become unstable and experience reshaping during the propagation process. then, interference occurs between the successive crescent-shaped pulses and multiple self-focusing can form. |
