We describe a next-generation monoblock laser capable of a greater than 10   mJ , 1.5 μ m output at 10   pulses / s   ( pps ) over broad ambient temperature extremes with no active temperature control. The transmitter design is based on a Nd:YAG laser with a Cr 4+ passive Q switch and intracavity potassium titanyl phosphate optical parametric oscillator. To achieve the repetition rate and efficiency goals of this effort, but still have wide temperature capability, the Nd : YAG slab is end pumped with a 12-bar stack of 100   W (each) diode bars. Different techniques for focusing the pump radiation into the 4.25   mm × 4 .25   mm end of the slab are compared, including a lensed design, a reflective concentrator, and a lens duct. A wide temperature operation (−20 °C to 50 °C) for each end-pumped configuration is demonstrated.
