Multilayer YAG/Yb:YAG Composite Ceramic Laser

Laser performance of a multilayer YAG/Yb:YAG composite ceramic fabricated by nonaqueous tape casting was demonstrated in a diode-pumped three-mirror cavity. We obtained a maximum continuous-wave output power of 3.6 W at 1051 nm with an absorbed pump power of 20.1 W, corresponding to a slope efficien...

Description
Summary:Laser performance of a multilayer YAG/Yb:YAG composite ceramic fabricated by nonaqueous tape casting was demonstrated in a diode-pumped three-mirror cavity. We obtained a maximum continuous-wave output power of 3.6 W at 1051 nm with an absorbed pump power of 20.1 W, corresponding to a slope efficiency of 28.6%. The composite ceramic laser wavelength-tuning characteristics were experimentally compared with fused silica, SF10, SF14, and SF57 dispersive prisms inserted in the laser cavity. An optimum smooth wavelength-tuning curve from 1008 to 1053 nm was achieved by using an SF57 Brewster prism.
