“…Later, following developments in laser technology, non-Fourier thermal behaviour was observed in short-pulse laser processing of thin-film engineering structures [3,4]. A similar phenomenon has also been experimentally observed in materials with non-homogeneous inner structure [5], such as H acid, NaHCO 3 , sand, glass ballontini, ion exchange, and sand with an irregular grain structure, which are similar in heterogeneity to biological tissues.…”
