*3.2.3 Establishment of laser power conditions*

In order to establish the most favorable parameters for the generation of primary pyrolysates, the laser energy, and irradiation time, among other laser conditions must be varied. These variations also provide a characterization of the performance and influence on the technique. **Figure 4** shows the spot size diameters obtained from a test performed in a Torbanite sample using different laser energy (13–20 A) at the same irradiation time (0.5 s).
