Liquid-assisted laser processing (LALP) is implemented using a 10.6 μm continuous-wave (CW) CO₂ laser to drill holes in 1.1 mm thick soda-lime glass substrates fully immersed in a nanoliquid bath. The nanoliquid bath consisted of de-ionized water and carbon nano-particles (CNPs) of different wt.%. The study focuses on the influence of exposure time (T_E, [s]), laser beam power (P, [W]) and number of pulses (N_P) on resulting geometrical features, namely, crack length (CL, [mm]), inlet diameter (D_INLET, [mm]) and exit diameter (D_EXIT, [mm]). The processed samples were characterized using an optical microscope. Findings show that LALP with investigated ranges of control parameters T_E (0.5–1.5 s), P (20–40 W) and N_P (1–6 pulses) led to successful production of drilled holes having CL range (0.141 to 0.428 mm), D_INLET range (0.406 to 1.452 mm) and D_EXIT range (0.247 to 1.039 mm). It was concluded that increasing T_E alone leads to increasing CL, D_INLET and D_EXIT, while keeping a good balance among the control parameters, especially T_E and N_P, will result in reduced CL values. Moreover, process statistical models were developed using statistical analysis of variance (ANOVA). These models can be used to further understand and control the process within the investigated ranges of control and response parameters.
