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.
