Abstract:  Recent laser driven reconnection (LDMR) constructed with self-generated B fields has been experimentally and theoretically studied extensively, where more than Mega-Gauss B fields are spontaneously generated in high-power laser-plasma interactions, which located on the target surface and produced by non-parallel temperature and density gradients of expanding plasmas. For the properties of short-lived and strong B fields in laser plasmas, LDMR opened up a new territory in a parameter regime not covered before. In this talk, I will present the recent LDMR experimental results performed on Shenguang and Gekko laser facilities, which are aimed to understand the basic physical processes, such as particle acceleations, scale of hte diffusion region, and guide fields' effects et al, which are also strongly interested in astrophysics plasma environments.
