…possible. Close to this threshold value, lift-off delamination was incomplete and uncontrollable. For the proposed PI glass system, optimum lift-off conditions slightly above the ablation threshold were achieved at a fluence value of 235 mJ/cm2 . Increasing the fluence to a value beyond 250 mJ/cm2…

…new machining qualities that result from a non-thermal ablation effect. On a femtosecond time scale, material ablation works similarly to vaporization by breaking of chemical bonds, but without a melting step. Peripheral areas of the ablation zone are hardly affected because the thermal penetration…
