Generation of highly ionized cadmium plasma columns for a discharge-pumped Nickel-like Cd laser
MetadataShow full item record
We report the observation of strong line emission from Ni-like Cd ions in a capillary discharge plasma. Spectroscopically pure Cd vapor was produced in a room temperature environment utilizing a capacitive discharge. The metal vapor was injected into a capillary channel where it was subsequently excited with fast current pulses of up to 200 kA These results open the possibility of observing laser amplification in the 3d94d-394p line of Ni-like Cd at 13.2 nm and in laser lines of other Nickel-like ions in a discharge-created plasma.
