Abstract
The laser-induced material removal and plasma formation during pulsed laser deposition (PLD) with CO2 and excimer laser radiation are simulated. The weight loss of the target is determined by the process of heating and the dynamics of the plasma state above the target. The plasma state depends on the wavelength and the fluence of the laser radiation and the pressure of the processing gas. In the case of C02 laser radiation the plasma state influences the weight loss significantly, while in the case of excimer laser radiation there is less influence.
