摘要：

Nanosecond laser ablation regime is investigated for the case of thin liquid Al film heated with constant radiation intensity I = 33MW/cm(2). The film dimensions are xxyxz = 448.7x37.3x37.3 nm(3) with periodically boundary conditions in y-z directions. The results of molecular dynamics modeling show four repetitive explosive boilings during laser action (5.6 ns) with attained maximum sample temperature 7000 K and recoil pressure 800 bar compared with calculated critical temperature 7630 K and critical pressure 1415 bar.
