“…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.

In water-guided laser technology, the stability of water jets is crucial to ensure the efficient transmission of laser energy. However, the thermal effects generated when high-power lasers are coupled with water jets are bound to impact the stability of the water jets, thus becoming a critical issue that restricts the development of high-power water-guided laser technology. In addressing this issue, this paper establishes a temperature model for coupling high-power lasers with water jets. Subsequently, with validation of the model's effectiveness through experimental data, simulations are conducted to analyze the temperature distribution within the water jet. During the simulation process, lasers with different parameters were coupled with water jets to analyze the temperature variation law of the water jets. Additionally, the maximum laser power coupled with water jets of different lengths was solved. Based on the calculated temperature values of the water jet, simulate the evolution of its profile over time when it has an initial temperature gradient. Simultaneously, perform a three-dimensional reconstruction of the obtained perturbed profile and conduct ray tracing to analyze the laser's transmission losses within the perturbed profile. Finally, high-speed cameras are utilized to capture the profile of the water jet, validating the laser-induced fragmentation behavior in the water jet. The research findings will provide a significant reference value for selecting laser parameters and controlling thermal effects in water-guided high-power technology.
