An experimental investigation has been done on the CO2 laser in order to study the feasibility of applying this laser to the water-jet-guided laser cutting technique. The characteristics such as water jet quality, reduction of heat affected zone, laser beam divergence, total internal reflection of light in water jet, and limitations in using the CO2 laser in the laser micro-jet cutting technique are studied computationally and experimentally. The chamber is designed using CATIA, analyzed with the ANSYS and fabricated by the CNC machining with employing AA6061. The value of 50 mm is found to...
