ABSTRACT:
An laser with improved output power is provided. The laser comprises: a cylindrical laser medium mounted on the shaft of a motor; a resonator including a pair of mirrors provided adjacent the opposite ends of the cylindrical face of the laser medium; and a multiplicity of laser diodes angularly spaced along the circumference of the cylindrical medium and upstream of the resonator in the sense of the rotation. The laser diodes optically pump regions of the medium facing the diodes. By rotating the cylindrical medium at a high speed, the pumped region of the medium will be brought into the resonator within the life lime of excitation, thereby increasing inverted distribution of energy per unit time. The pumped regions sequentially undergo laser emission, providing increased laser output power.
