Research Abstract

This work aims evaluation of structures and acoustic properties of samples which has nano/micro-scale structures on surface or innards by use of nanometer and picosecond widths' ultrasonic pulses which is generated and detected by nondestructive and noncontact optical method. This experiment bases on laser picosecond ultrasonic techniques by use of a femtosecond pulse laser. I measured ultrasonic fields in a gold wedge sample (0-2000 nm thickness) on a silicon-nitride membrane (100 nm thickness), and reflections of ultrasonic pulses at microstructures on a silicon wafer.
