    Abstract

    This paper reports an extension of recent where elemental CVL performance can be improved. In particular, it was recently demonstrated a doubling of the output power from two medium-scale CVL devices. The first CVL (25mm diameter by 1m active region, employing conventional switching technology) normally produced up to 25W when operated under conventional operating conditions. However, output powers of 50W were routinely obtained from this same device by engineering the kinetics in this device. The second CVL (40mm by 1.5m active region, employing 3-stage magnetic pulse compression excitation) was improved from the 50-55W level to 100W by these techniques. Furthermore, the specific power extraction of the 40mm CVL device (53m W cm -3) is similar to that obtained from copper HyBrID lasers of similar active volume (ie 50 mWcm -3 for a 120W Cu HyBrID [4]). Sealed-off high power operation of these improved CVLs has also been demonstrated. It is significant that these power enhancements are achieved with little change to conventional CVL technology.
