Development of laser shock peening technology: from short pulse duration (nanosecond) to ultrashort pulse duration (femtosecond)

Caption

This article reviews advances in laser shock peening (LSP) across nanosecond to femtosecond pulse duration, highlighting that nanosecond LSP enables surface strengthening and fatigue resistance via gigapascal-scale shock pressures, whereas femtosecond LSP achieves ultrahigh-pressure, high-precision, low-deformation strengthening and integrated functional fabrication without confining and absorbing layers.
