Copper laser with high-average-output power

Two kinds of lasers are reported: CuBr and CuHyBrID lasers producing an average output power of 6.7 W and 9.5 W respectively of an active volume of just 4.77 cm3. These values correspond to record specific output powers of 1.4 W/cm3 and 2.0 W/cm3 respectively for these lasers and for the copper ones in general.
