Abstract
A high power solid state laser has a solid state laser medium with two ends and a longitudinal axis, at least one laser diode configured to end pump the laser medium, a resonator in optical alignment with the laser medium, a transparent and thermally conductive end cap disposed at each end of the laser medium and in thermal communication therewith, and at least one heat sink in thermal communication with the end caps. The end caps and the heat sink(s) cooperate to effect heat flow from the laser medium such that a substantial component of the heat flow is along the longitudinal axis of the laser medium, thus mitigating undesirable transverse temperature gradients within the laser medium and enhancing average power output therefrom.
