Abstract :
In the laser etching of surfaces, the gas-surface chemical reaction used may be spontaneous or induced by a laser-gas interaction. We put into evidence a third mechanism allowing to use gas molecules that interact directly neither with the surface nor with the laser but that contains reactive atoms.
