A scalable diode-pumped Nd:YAG laser is described in which the grain element resembles a penta-prism. This design allows longitudinal pumping along five separate axes. Using five high-power single strip laser diodes, 4.16 W of absorbed power produced 2.3 W CW at 1.06 [mu]m. The slope efficiency was 56%, the output was plane polarized, and the laser operated in the TEM[sub 00] mode. The threshold power was 48 mW. No evidence of thermal saturation was observed up the maximum pump power. With an intracavity KTP crystal, 341 mW of CW amplitude-stable output at 532 nm was generated. Repetitive Q-switched operation is also reported.
