Abstract

Abstract. We study numerically the collapse behavior of self-generated magnetic fields described by the nonlinear coupling equations in laser-produced plasmas. The results show that magnetic fields self-generated by transverse pumping plasmons near critical points may collapse, leading to the enhancement of magnetic fields about up to 0.18 MG and 1.8 MG at laser irradiances of 1012 W cm−2 and 1016 W cm−2 respectively, which are similar to the experimental results.
