Laser spectroscopic studies of pulsed-laser deposition process for high-Tc thin films

In order to investigate the particle-behavior in the pulsed-laser deposition (PLD) process for high-temperature superconducting (high-Tc) thin film fabrication, laser-spectroscopic techniques have been applied. Laser-induced fluorescence spectroscopy (LIF) was used to obtain the detailed information on the behavior of non-radiative atomic and molecular species in their ground states. Mie scattering was also successfully used to monitor the production of the particulate in the ablated plume. Visualization of the propagating plume is also presented.
