The temperature dependences of laser induced plasma thresholds for copper, iron, and chrome with linearly and circularly polarized pulses from a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (wavelength 1064 nm, pulse width 4 ns) were evaluated at different temperatures from 123 to 423 K. The temperature dependence of copper with linearly polarized pulses was different from those of iron and chrome. On the other hand, the dependences of all materials with circularly polarized light showed the same tendency. The geometries of the ablated sites presented interesting tendencies, revealing some aspects of interaction between metal materials and laser that warrant further investigation.
