摘要：

Nanosecond photoacoustic measurements of excimer laser ablated ceramic and thin film Y-Ba-Cu-O superconductors are reported that provide information on the ablation timescale threshold and surface pressure. Results for the surface pressure are found to be inconsistent with a simple surface vaporization model, suggesting that a different removal mechanism is operative. The outline of an alternative mechanism based on the concept of explosive removal is put forward.
