摘要:

We present measurements of high frequency ultrasound generated by a femtosecond laser pulse. Focussed on thin aluminum foils (8 – 80 &mgr;m), the measured ultrasonic spectrum extends up to a detection limit of 800 MHz. The high frequency ultrasonic echoes allow measurements of foil thickness down to 8 &mgr;m, the minimum foil thickness used in this set of experiments. © 2003 American Institute of Physics
