Aging changes in dynamics of ps sonar experiment in thin optical films: possible sources and consequences
We used the experimental pump&probe method of picosecond acoustics to show that the signal is prone to sample aging, partially reversible in vacuum. The aging can be eliminated by deposition of an Si 3 N 4 passivation layer.
