Water Jet Guided Laser Cutting Technology and Its Cooling Solutions

Water Jet Guided Laser (WJGL) represents a breakthrough in precision manufacturing, combining the cutting power of a laser with the cooling and guiding properties of a fine, high-speed water jet. In this technology, a micro water jet (typically 50–100 μm in diameter) acts as an optical waveguide that directs the laser beam to the workpiece through total internal reflection. This innovative approach not only stabilizes laser energy transmission but also provides real-time cooling and debris removal during processing — resulting in ultra-clean, high-precision cuts with minimal heat-affected zones.

Laser Sources in Water Jet Guided Laser Systems
Different laser types can be integrated into WJGL systems depending on the application:
Nd:YAG lasers (1064 nm): Widely used for their reliability and stable performance in industrial environments.
Fiber lasers (1064 nm): Favored for high-efficiency metal cutting, offering enhanced beam quality and energy efficiency.
Green lasers (532 nm): Improve laser-water coupling and enable greater precision in delicate material processing.
UV lasers (355 nm): Ideal for micro-fabrication and fine detail machining due to excellent water transmission and controlled material interaction.

Precision Cooling Solutions from TEYU
