Abstract

We have demonstrated 1.15  W of Gaussianlike M2=2 cw output at 2.94 μm from a diode laser end-pumped monolithic laser crystal composed of Er-doped yttrium aluminum garnet (YAG) bonded to undoped YAG. The laser was pumped with two polarization-coupled 2.5-W flared laser diodes that provided a 45μm pump waist with a low N.A.  <0.04. Output at 2.94 μm was generated with a 34% slope efficiency and a greater-than-unity quantum efficiency.
