Abstract
Optical measurements have been performed on pulsed laser ablation of c eramic (YBCO and PZT) and metal (Al and Ti) targets at a pulsed laser fluence in the range of 0.06-3.6 J cm(-2). Time resolved target reflec tivity measurements demonstrate the formation of a plasma layer able t o absorb the laser radiation above the target surface. Plume optical e mission measurements, collected both from the parallel and the normal directions to the plume expansion axis, enable an evaluation of the pl asma temperature and density as a function of the time after the arriv al of the laser pulse.
