Paper Abstract

We report a novel design of solid-state laser amplifier chain based on Nd:YAG gain mediums, by lining up multiple single-side-pumped slabs in a special manner. The scheme takes advantage of the excellent power scalability of the sidepumping configuration, and allows a reduction in cost and complexity comparing to the conventional way, by decoupling the cooling and pumping interfaces and thus avoiding water sealing application and water contamination to the crystal. Specifically, influences of ASE effects on the amplifier performance (power scaling, beam quality and transverse mode profile) are described in detail, considering the re-amplification of ASE along the slab chain. A point design at 10 kW power level including the ASE effect is also described.
