Abstract

The mass Δm removed per pulse in laser ablation was shown to correlate with the acoustic signal A and the beam diameter Φ. The functional forms of δm(A, Φ) were deduced for aluminum and polyvinyl chloride, for fluence ranging from 1.5 through 88Jcm-2 Δm so computed agreed with empirical values within experimental error. For samples whose mass is sensitive to environmental factors, off-line measurement of Δm was shown to be unreliable and real-time measurements such as acoustic monitoring became essential.
