Study on folded resonator of high power transverse flow CO2 laser

A numerical model of the folded resonator is founded by using the eigenvector method. The beam characteristics and relative amplitude distribution of dominant mode of the N-shaped three-folded resonator with different aperture diameter are obtained by numerical simulation. The experiment of the resonator is done on HUST5000 high power transverse flow CO2 laser. The results show that the mode volume of the N-shaped three-folded resonator with the aperture diameter of 25mm can match the gain zone of the transverse flow CO2 laser well, the output power and beam mode are fit for industrial applications. The laser welding system based on this resonator is developed for gas generator of automobile safety airbag.
