The evolution of nuclear structure in the magic nickel chain provides stringent tests of nuclear theory with the presence of three doubly magic nuclei ($^{48,56,78}$Ni) and a prominent subshell closure at $^{64}$Ni. In this work, precision laser spectroscopy measurements on $^{52,53}$ Ni will be presented, which extend the known Ni charge-radii chain beyond doubly magic $^{56}$Ni towards the proton drip line at $^{48}$Ni. The nuclear magnetic-dipole and electric-quadrupole moments of $^{53}$Ni will also be reported. From the difference in the $^{52}$Ni-$^{52}$Cr mirror pair charge-radii, a constraint on the slope parameter (L) in the symmetry energy of the nuclear equation of state will be deduced, analogous to the previously measured $^{54}$Ni-$^{54}$Fe mirror pair [1]. Details of the measurement technique and results will be discussed.
