Abstract

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.
