Paper Abstract

New methods of copper excitation are currently being studied for use as a copper vapor laser. The most promising technique thus far is the use of pulsed and continuous wave (CW) microwaves in a resonant cavity to both vaporize and dissociate copper chloride. The microwave experiment combines CW microwaves at 2.45 GHz, the resonant frequency of the cavity, and pulsed microwaves using a hybrid junction. The combined signal is then introduced into an Asmussen resonant cavity. CW powers of approximately 100 watts both vaporize and dissociate copper chloride, producing neutral copper atoms. The pulsed microwaves of approximately 1,000 watts then further excite the copper atoms, increasing the light output of the discharge. Variations in the pulsed microwave frequency, as well as the pulse repetition frequency and pulse width, optimize the absorption of the pulsed microwaves by the discharge and are also used as a diagnostic of the discharge.
