Abstract

We report on initial testing of an edge-pumped Yb:YAG disk laser. The assembled laser uses two laser disks having a composite ceramic construction with undoped perimetral edge 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. This work presents results of initial testing of the laser with one Yb:YAG laser disk and resonator optics configured for power extraction with two passes through the disk.
