Spatial and temporal effects due to target irradiation: a study

A dynamic IR high temperature target is activated by. scanning a high power laser beam on its surface. The laser dwell time determines the amount of power deposited at a particular location. Temperature distribution is calculated resulting from the laser deposited power as a function of position and time. The power necessary to heat the target and maintain the target temperature distribution is evaluated. The effects of heat saturation in time and place are examined for a general irradiation study in the case of a target with finite dimensions and the laser beam diameter of a size comparable to target thickness and width.
