## Abstract This study predicts the variation of surface absorptivity with temperature for structural ceramics such as magnesia (MgO), alumina (Al~2~O~3~), silicon nitride (Si~3~N~4~), and silicon carbide (SiC). In‐situ temperatures reached during pulsed 1.06 μm Nd:YAG laser low aspect ratio cavity
