Published findings are analyzed in relation to wavelength, pulse duration, fluence, and scanning conditions, while comparisons with other polymers clarify material-dependent responses. The reviewed evidence indicates that controlled irradiation can generate micro- and nanostructures, alter water contact angle, and improve interfacial conditions for polymer joining. A published polycarbonate\u2013polystyrene welding study reported a contact-angle decrease from 86.3\u00b0 to 43.4\u00b0 and a maximum joint shear strength of 13.65 MPa. Other observations show that wetting behavior may evolve with surface aging. Increased roughness does not invariably improve wettability, and improved joining does not establish increased hardness or wear resistance. The fluence\u2013contact-angle regression included in this paper is treated as an illustrative calculation rather than original experimental evidence. The review concludes that laser processing offers a versatile route to functional polycarbonate surfaces, provided that performance gains are assessed alongside transparency loss, thermal damage, and long-term stability using application-specific characterization.<\/p><p style='text-align:left; direction:ltr;'><strong>Keywords: <\/strong> Polycarbonate; Laser processing; Surface roughness;
