“…Due to the cooling effect of the water jet, the material processed by water-guided laser technology does not produce thermal damage, and the rapid flushing of the water jet can better remove the slag during processing and prevent the formation of recast layers. Therefore, water-guided laser technology is an up-and-coming technology [1][2][3].…”

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.

“…Li and Achara [14] implemented laser machining assisted by an ECM process to minimize the recast layer associated with laser machining. A similar process water jet guided laser [15] enables clean cutting of materials but in this technology the liquid does not provide cutting energy and only serves to guide the laser and to cool the machining zone. Sequential electrodeposition and thermal activation by high pulsed electron beam has also been reported for production of durable hydrophobic structures by invoking bead phenomenon [16].…”
