Stacks of intrinsic Josephson junctions (IJJs) in high-temperature superconductors enable the fabrication of compact sources of coherent terahertz radiation. Here we demonstrate that multiple stacks patterned on the same Bi2Sr2CaCu2O8+delta crystal can - under optimized conditions - be synchronized to emit high-power THz-radiation. For three synchronized stacks we achieved 610 microwatts of continuous-wave coherent radiation power at 0.51 THz. We suggest that synchronization is promoted by THz-waves in the base crystal. We note though that synchronization cannot be achieved in all samples. However, even in these cases powers on the 100-microwatt scale can be generated.
