Thermal - hydraulic phenomena adjacent to the liquid metal - water and solid material - water interfaces induced by nanosecond pulsed Nd : YAG laser (wavelength : 532 nm, FWHM : ~ 13 ns) heating with the fluence F of 5.0 × 10(1) ~ 1.0 × 10(3) mJ/cm(2) were experimentally investigated. By applying the high - speed photography with a frame speed up to 2.0 ×1 0(7) fps, the aspects of the bubble formation, shock wave generation and propagation were observed. The bubble formation on the heated material's surface of about 80 nm in diameter was detected in Si - water system from the time-resolved reflection (TRR) signal by applying the pump and probe method.
