Abstract

In order to meet the special demands for laser materials processing, after the analysis and design of the resonator parameters and pulse parameters, a mechanical chopper Q-switched CO₂ pulse laser unit is developed. At last, a Q-switched CO₂ laser pulse with high peak power of more than 10kW and the maximum beam power of 800W (at this time the pulse repetition rate is 20kHz) and TEM₀₀ mode is obtained. The width of the pulse duration is adjustable and in order of μs.
