glass and two different types of alkali-free glass samples. These typical data show the ablation rate decreases vary slightly as the hole gets deeper in all the samples, as is typical for laser micromachining of glass. They also clearly show that the ablation rates for borosilicate glasses are much…

…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…
