Laser beam effects on Cu and Ti in vacuum and in the air
Ti and Cu samples were exposed in ambient atmosphere and vacuum (0.66 mPa) to single pulse (0.2–2.6 J) ruby laser radiation in the Q-switch (30 ns) and free generation regimes (150 μs). Acoustic recordings during irradiation were carried out and the resulting damage was analyzed by light and scannin...

Summary: | Ti and Cu samples were exposed in ambient atmosphere and vacuum (0.66 mPa) to single pulse (0.2–2.6 J) ruby laser radiation in the Q-switch (30 ns) and free generation regimes (150 μs). Acoustic recordings during irradiation were carried out and the resulting damage was analyzed by light and scanning electron microscopy. In contrast to vacuum conditions, it is observed in the air that the damaged area was much larger due to plasma effects and also that cracking of the Ti samples and oxidation of the Cu samples occurred. |
