Baer, T M

This patent describes a mode-matched diode pumped solid-state laser amplifier system including amplifier stages, each of the stages include a block of laser amplifier material having a pair of opposed sides, a tightly folded zig-zag optical path within the block between the opposed sides having vertices at a preselected fold angle, the fold angle being selected to substantially match the mode volume with pump radiation from the pump sources, a plurality of laser diode pumping source positioned adjacent to at least one of the opposed sides and substantially aligned with the vertices of the zig-zag optical path, the amplifier stages being optically coupled to one another in a cascade arrangement.
