Abstract
We report on initial testing of an edge-pumped Yb:YAG disk laser having a composite ceramic construction with undoped perimetral edge. The edge is designed to channel pump light while efficiently outcoupling amplified spontaneous emission (ASE). Edge-pumping allows for reduced doping of crystals with laser ions, which translates to a lower lasing threshold in Yb:YAG material and much reduced waste heat flux. Uniform gain and stable lasing were achieved.
