heal.abstract	Excimer laser may be used in the micromachining of various materials, especially in cases where surface finishing by a conventional machining method is difficult. In this study, the process was applied onto two high performance alloys: CMSX2 and TA6V, widely used in the aircraft industry. An attempt was made to determine the relationship between the laser parameters (fluence, frequency, pulse number) and the shape of the formed craters, the proportion of the ablated material and the laser hardening effects. Energy density of 2.5 kJ.cm(-2) was found to be the critical value above which the amount of material ablated and resolidified tend to a constant rate, while the depth attained was influenced only by the other laser parameters (frequency and number of pulses). For the highest energy density applied (10.2 kJ.cm(-2)) the formed craters were cone-shaped, in the case of CMSX2, and rectangular, in the case of rolled TA6V. In fact, a prior rolling procedure of TA6V had a great influence on the ablation mechanism. Shock waves occurred hardening affect only the region of CMSX2 sub-surface.	en
