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.
