Abstract:
The fundamental properties (electron temperature and density) at the early-stage evolution of plasma induced by laser-ablated KTiOPO(4) crystals are analyzed using an emission spectroscopy technique. The comparative studies give detailed insights into the influences of laser intensity and wavelength on the temporal evolution of the plasma. The lifetime of the plasma strongly depends on the laser intensity. The 532 nm laser beam can create hotter and denser plasma with faster expanding velocity than the 1064 nm laser beam.
