Abstract
The effects of an external magnetic field on Nd:YAG laser-produced Sn plasma have been investigated. The characteristics of ion debris from Sn plasma, emission spectra, and EUV radiation have been studied by the time-of-flight method and the optical emission spectroscopy. Our results show that the ion kinetic energies of the plume species can be effectively reduced with a modest magnetic field of 0.6 T. With the presence of a magnetic field, the spectral intensities of Sn I and Sn II show significant enhancement and the electron density of plasma is about 2 times higher. We have not found any influence of magnetic field on the characteristics of EUV emissions.
