  • In the all-metal radio frequency excited CO2 laser,the temperature distribution in the discharge region varies with the gas mixture,input power and the background temperature.Besides the above factors,the thickness of the metal crust and the insulated gas width between the crust and metal electrode will also affect the temperature distribution to some extent.The temperature distribution in the discharge region is analyzed,which provides a good reference of designing the laser structure and selecting the gas mixture.

Abstract: In the all-metal radio frequency excited CO2 laser,the temperature distribution in the discharge region varies with the gas mixture,input power and the background temperature.Besides the above factors,the thickness of the metal crust and the insulated gas width between the crust and metal electrode will also affect the temperature distribution to some extent.The temperature distribution in the discharge region is analyzed,which provides a good reference of designing the laser structure and selecting the gas mixture.
