CYCLOTRON RESONANCE PUMPING OF GAS LASERS.
Abstract
Experiments employing pure d-c pumping and combined d-c/microwave cyclotron-resonance pumping are being performed on argon lasers. Effort is being directed toward understanding the effects of these pumping combinations on discharge behavior and laser operation. Experiments with combined d-c and microwave pumping were also made. A larger microwave cavity with improved r-f contacts was designed and built for these experiments. Results show that threshold was obtained with 500 watts microwave power added to 300 watts d-c (5 amperes at 60 volts) for a total of 800 watts. This was considerably below the 1040 watts (13 amperes at 80 volts) required with pure d-c pumping. In addition much of the microwave power was wasted as radiation from the ends of the cavity. Further improvement in performance is expected after provisions have been made to better confine the microwave energy to the cavity.
