What are the application fields of water guided laser?

The research on the principle of water-guided laser processing involves multiple disciplines such as laser, material, fluid, heat transfer, etc., and is highly interdisciplinary. The coupling technology of water and laser is the key technology of this processing method. The laser beam is expanded and focused into the nozzle hole. When the incident angle of the laser is greater than the critical angle of total reflection, the laser is fully emitted at the water-air interface. Under the guidance of water, the laser maintains a constant laser energy density and reaches the processed material Surface.

It has been widely used in material cutting in aerospace field.
