Abstract
Methods, systems and apparatus are provided for amplifying a source light in a solid state laser. An amplifier module for the solid state laser suitably includes a disk having two substantially parallel surfaces and an optical gain material. A number of diode bars are arranged about the perimeter of the disk and configured to provide optical pump radiation to the laser gain material in the disk. Each of the plurality of diode bars is spatially aligned with the disk in such a manner as to produce substantially uniform gain across the optical gain material. The fast axes of the diode bars maybe aligned to be parallel or orthogonal to the parallel surfaces of the disk, for example.
