Residual Heat in Ultra-Short Pulsed Laser Ablation of Metals

Abstract

In ultra-short pulsed laser ablation of metals, a considerable amount of the incident laser energy remains in the workpiece as residual heat. When using high repetition rates, this can cause severe damage due to heat accumulation effects. In this paper, the amount and the spatial distribution of the residual heat deposited by a spatially Gaussian-shaped laser pulse are investigated by means of calorimetric measurements.
