Copper HyBrID lasers are the most efficient high-power lasers that generate directly in the visible spectral region. In HyBrID lasers, copper bromide is produced in situ in the laser active region by the reaction of hydrogen bromide, which is added to the flowing Ne buffer gas, with pieces of copper metal there. The copper bromide is then dissociated in the high pulse recurrence frequency discharge to yield free copper atoms, and laser oscillation in neutral copper atoms is generated at 510.6 nm and 578.2 nm by electron impact pumping at the beginning of each current pulse. In order to determine the average-power scaling laws of these lasers, it is important to investigate the maximum output power that can be generated from a given volume of the active medium, and the discharge conditions for which it can be achieved. By this means, it may be possible to develop more compact high-power lasers for the visible spectral region. The scaling dependences also yield valuable information regarding kinetic processes in the laser discharge. Here, a copper HyBrID laser ({lambda}510.6, 578.2 nm) is reported, which produced an average output power of 9.5 W from an active volume of just 4.77 cm{sup 3}. These figures correspond to a record specific average output power for copper lasers of any type of 2.0 W/cm{sup 3}.
