Laser applications in manufacturing processes such as cutting, welding, and engraving processes are become more popular nowadays. High-power and pulsed lasers such as CO2 and Nd:YAG gas lasers are commonly used in applications of metal cutting and welding. Meanwhile, for engraving process laser diode is more preferred due to its properties of compact shape, easy to operate, low power and high efficiency...
Applicability of the acousto-optic method for raising the time-averaged thermal efficiency of laser radiation is substantiated theoretically and confirmed experimentally. The effect produced by laser radiation on materials being processed (laser cutting, welding, engraving, etc.) has a threshold in light intensity. Importantly, a beam with the most frequently used normal (Gaussian) angular distribution...
