- W2897834202 abstract "A mechanical chopper Q-switched CO2 pulse laser with 15kW peak power, 6 μ s pulse duration, 20kHz pulse repetition rate, 500W average power and near Gaussian mode is developed. Using this laser, a multi-pass cutting process with high cutting speed is proposed for cutting hard and brittle materials such as engineering ceramics. Crack-free and fine cut is obtained in cutting Si3N4 ceramics. Moreover, the mechanism and parameter optimization of the process are qualitatively analyzed in the paper.A mechanical chopper Q-switched CO2 pulse laser with 15kW peak power, 6 μ s pulse duration, 20kHz pulse repetition rate, 500W average power and near Gaussian mode is developed.
