1. A mode matched diode pumped solid state laser, comprising:

  • a block of laser material having a pair of opposed sides;

    cavity forming means positioned around the block to define a laser cavity having a tightly folded zig-zag resonator portion within the block between the opposed sides at a preselected fold angle;

    a plurality of linearly spaced laser diode pumping sources positioned adjacent to one of the opposed sides and substantially aligned with the zig-zag portion of the resonator;

    the fold angle being selected to substantially match the mode volume with pump radiation from the pump sources.
