摘要：
A mechanical chopper Q-switched CO, pulse laser with high peak power, short pulse duration, high pulse repetition rate and moderate average power is developed. Using this laser, a cutting process of high cutting speed and multi-pass is proposed for cutting hard and brittle materials such as engineering ceramics. Crack-free and fine cut is obtained in cutting Si3N4 ceramics.
