Abstract: Among the recent topics of photothermal (PT) applications
of lasers, we focus on ultrafast (<=1.0 ns) photothermal/photoacoustic
(PT/PA) phenomena occurring at interfaces, which play important roles
in nanoscale materials science and technology. Here, we describe our
recently developed novel PT techniques called transient reflecting grating
(TRG) spectrometries. These techniques have been applied to the studies
of solid surfaces, film substrates, and solid/liquid interfaces.
