Cold laser material processing has relied on the use of high-peak-power lasers in order to reach the universal threshold for plasma formation of ~1 J cm−2in most solids. Here, the authors show a cold ablation process that takes off below both the threshold for plasma formation and that of the melting point of alkali halides.
