Paper Abstract

The high-power laser beam interaction with the surface of metals (W, Fe, Ti, stainless steel) has been studied under high external pressures of the inert (Ar) and active (O2) gases. The velocities of punching the samples have been measured at laser pulse power densities I equals 0.5 multiplied by 106 - 107 W/cm2 in the beam revealed in punching velocities depending on the type of external gas. The dynamics of variations in the shape of high-power laser pulse reflected from the surface (W, Fe, Ti) has been studied.
