Deformation of partially pumped active mirrors for high average-power diode-pumped solid-state lasers.

We discuss the deformation of a partially pumped active mirror amplifier as a free standing disk, as implemented in several laser systems. We rely on the Lucia laser project to experimentally evaluate the analytical and numerical deformation models.
