摘要

The study of the elastic properties of liquid micro-layers is of importance in biology and in micro-technology. Generation of the ultrasonic waves by sub-nanosecond pump laser provides opportunities for non-contact and non-destructive evaluation of materials at spatial scales from micrometer to a few tens of micrometers. Here, we report on the application of this all-optical technique for the study of acoustic properties of liquid layers of micrometric thickness confined by two parallel solid plates.
