Abstract
We report the first observation of a laserproduced vibration with the aid of Mössbauer techniques Thin platelets of MgO single crystals were doped by diffusion of 57Fe atoms The illumination of the MgO57Fe sample with a pulsed NdYAG laser produced a significant broadening of the Mössbauer spectrum In order to find out what caused these changes we performed a series of timedomain experiments in which the Mössbauer spectra were collected only during a 25 μs gate interval This gate interval was swept from 5 μs to 190 μs over the time interval between the two laser pulses After laser irradiation the position of the Mössbauer line was found to be changing in time as a decaying oscillations of welldefined frequency which can be due to the vibration of the sample induced by the laser pulse
