Features of a single crater formation under the influence of the impulse of laser radiation on the material

Аннотация

The basic features of the formation of a single crater under the influence of the pulse laser radiation on the surface of the titanium alloy and corrosion-resistant steel specimen are experimentally confirmed. In addition, a possible influence of the plasma–vapor cloud on the single crater formation. A calculation was carried out of an approximate estimate of the index, connecting the material mass destroyed under the impact of the phase transition with the absorption energy. This makes it possible to perform specific technological calculations needed while preparing for laser marking and milling.
