“…Huang et al [25] proposed a deflected water beam-guided laser method based on a nonuniform electric field for the water-optic coupling process. In the coupling of the laser and the water beam, the problem of the laser easily burning the nozzle and deviating from the set ablation area was effectively solved.…”

As an emerging industry, laser processing technology has developed rapidly and has gradually become a key technology in transforming traditional manufacturing. It has been widely used in various fields such as industrial production, communication technology, information processing, health care, military, and scientific research. The application and development of laser processing technology is restricted by thermal damage and the processing residues existing in traditional laser processing. However, water laser compound machining can better solve the above-mentioned problems. In water laser compound machining, heat and byproducts can be absorbed and taken away by water to improve processing quality. This paper expounds and analyzes the principles and research of three popular water laser compound machining methods (water-guided laser processing, underwater laser processing and water-jet-assisted laser processing). Furthermore, this paper analyzes the technical difficulties in water laser compound machining and looks forward to the future development trends of this technology.

“…ZHANG et al proposed a new water-air contraction-guided high-power laser processing technique capable of directly coupling a high-power laser into a water jet and improving the stability of laser transmission [8]. The emergence of bending water-guided laser technology is also an effective solution to ensure the coupling of high-power lasers to water jets, using a non-uniform electric field to twist the water jet, which allows the high-power laser to be coupled directly to the water jet without passing the nozzle, which avoids damage to the nozzle caused by the high-power laser [9,10]. In the total energy set model developed by MULLICK et al, the absorption effect of water on the laser beam is the main part of the energy loss [11][12][13].…”

Water jet-guided laser is a new type of processing technology. With the continuous emergence of high hardness, high strength materials and the demand for high-efficiency processing, water jet coupled high power laser has become an inevitable trend in the development of the water-guided laser, and high-power laser energy and water jet coupling transmission and processing process will bring a series of problems such as transmission loss, these will become one of the key issues limiting the development of this technology. Therefore, studying the transmission loss of high-power laser energy guided by water jets is necessary. In this paper, we address this problem by numerically solving Maxwell's set of equations using the finite element (FEM) method and performing wave optical simulations of high-power laser transmission in a water jet to obtain the electric field distribution of the laser beam in the water jet, and explore the relationship between laser wavelength, laser spot diameter, water jet diameter and length, and laser energy loss. Finally, laser energy transfer efficiency measurement experiments were conducted to verify the model's validity by comparing it with simulation data. The study's results will provide some implications for regulating the transmission efficiency of high-power lasers in water jets.

To study the effects of aluminum alloys processed by a laser in air and water and at different water velocities, corresponding experiments were conducted and the impacting effects of different water velocities on the surface of the workpiece were simulated, respectively. The results show that when laser processing aluminum alloy materials in air, there is more slag and a recondensation layer on both sides of the groove, the heat-affected zone is larger and the surface processing quality is poor. When laser processing aluminum alloy materials in water, the processing quality is improved. With the increase in water velocity, the impacting and cooling effect is enhanced, the groove depth and groove width show a trend of first increasing and then decreasing, the slag and recondensation layer on both sides of the groove are reduced, the heat-affected zone is reduced and the processing quality of the groove is improved. When the water velocity reaches 30 m/s, a better groove can be obtained. Laser processing aluminum alloy materials in water can obtain better processing quality than laser processing in air.
