Abstract
The influence of a dc external magnetic field B0 on the output power of a rf excited CO2 laser is considered. The voltage-current density characteristic curve, electron temperature, deposited power, and gas mixture temperature of the plasma are numerically investigated in the presence of the external magnetic field. The electric discharge of the magnetized rf excited CO2 laser is seen to be stable. It is shown that the deposited power into the plasma increases with increasing magnetic field intensity. Mean temperature of the gas mixture of the magnetized rf excited CO2 laser is computed as a function of B0, which is substantially increased at a relatively strong B0. An experimental setup is conducted to measure the output power of a rf excited CO2 laser in the presence of B0. It is found by applying B0 upon the laser the output power increases.
