A pulsed laser was used to irradiate the surface of a HgCdTe target, and a time and space resolved diagnostic technique was used to detect the emission spectrum from the plasma. The ejected velocity of the plasma was measured by using obtained time of flight curves. According to the shape of the continuum, the plasma temperature was calculated using the Plank′s formula. On the basis of the experimental results, the properties of the HgCdTe plasma were discussed.
