Abstract:
The sel-f focusing effect of quas-i double-r ing modulated laser beam propagating in the Kerr-medium CS2 has been observed in the experiment. In theory, the nonlinear Schrǒ Odinger equation is solv ed by means of setting up a modulated laser beam model. The forming process and the character istics of the sel-f focusing are descr ibed in detail. Finally , the coupling effect of the double- ring laser beam has been investigated and the character istics are given.
