We report on testing of an edge-pumped ceramic Yb:YAG disk laser for pulse amplification under intense pumping. The disk has a composite construction with Yb-doped central portion cosintered with an undoped perimetral edge. Light from multi-kW pulsed diodes is transported though the disk edge and absorbed in the Yb-doped center. This configuration results in a very simple and compact laser gain module. The disk is operated as a storage amplifier. Amplified spontaneous emission and parasitic lasing is alleviated by the geometry of the laser disk edge rather than absorption cladding. Our test results indicate that this approach offers a robust mitigation of ASE. This work presents results of stored energy, gain, and ASE mitigation in the Yb:YAG disk laser under intense pumping.
