“…The obtainable peak power density is dependent on the pulse durations. Thus, for millisecond laser drilling, it is reported to range 106-109 W/cm 2 , for nanosecond laser drilling in the range of 1-10 GW/cm 2 , and for ultrafast picosecond lasers used for drilling holes, in the range of 10-1000 GW/cm 2 , decreasing thermal effect on the zone drilled to very small values close to zero (Xia et al 2021). Accordingly, the quality and accuracy of holes are improved as the duration of the laser pulse becomes shorter (Nath, 2014).…”

“…Further improvement of laser drilling efficiency and quality can be obtained by means of magnetic field-assisted technique with or without assist-gas (Wang, Xu et al, 2019), water assistance (Ren et al, 2020), ultrasonic assistance (Xia et al, 2021), electrochemical corrosion assistance (Duan et al, 2020), etc. For example, in the case of femtosecond laser drilling in alumina ceramics, the effect was considerably increased by water assistance, with the taper angle diminishing by 64.19% to 4.20° and the hole cross-section area increasing by 46% (Ren et al, 2020).…”

“…Their findings demonstrate that the quality of the cutting edge might be raised by selecting the most suitable and ideal parameters for the procedure. The effects of assist gas pressure, laser pulse energy and ultrasonic vibrations on the laser drilling process were examined by Xia et al [21] Their findings demonstrate that selecting the appropriate drilling parameters can improve the quality of the cutting surface. In a laser drilling procedure on magnesium alloys, Wang et al [22] examined cutting quality both with and without submersion in water.…”

In this study, an efficient approach was proposed to systematically model and optimize the laser small hole cutting process parameters using a hybrid approach for the design of experiment and multi-objective genetic algorithm optimization. The central composite design and response surface methodology were used to effectively model the impact of four main factors: cutting speed, laser power, gas pressure and focal distance on the responses. The responses considered were hole diameter circularity tolerance, spattering and cut kerf width, which were used to evaluate the quality of the laser hole cutting. The regression equations were used to model the effect of process parameters and their interactions on the responses. These regression models were then used as objective functions for optimization. The results show that the focal distance and laser power have had a significant influence on the hole diameter circularity tolerance and the variation in size of the cut kerf. In particular, the melted material spattering rate increased threefold when the focal distance increased from 0.4 to 0.8 mm. The optimization results highlighted that the best outcomes in terms of minimum deviation, spatter, and the cut-kerf width were achieved at low power (between 605 and 685 W) and low speeds (in the range of 11.1–12.7 m min−1). The optimal focal distance for all solutions was found to be 0 mm for the gas pressure (between 6.5 and 8 bars) to minimize the objective functions.
