Millisecond transient response of photo-induced deformation in ternary thallium compounds

Abstract

The time-resolved photo-induced deformation phenomena in ternary thallium compounds has been investigated with milliseconds pulsed laser beams. Appropriate pump pulse width to increase the deformation is found by tuning the width of pump pulse in the experiment, and the results show the phenomena is dueto the thermal expansion by the rapid temperature raise around the pump spot region.
