    • A solid state laser medium comprising at least one cooling element, i.e. cooling element, in contact with and alternating in series with at least one gain element. At least one cooling element and at least one gain element are joined at an interface having a center point, wherein the interface is physically modified at the interface such that the heat transfer coefficient at the interface decreases radially from the center point of the interface. The modified interface promotes thermal transfer from the gain element in the axial direction, in such a manner as to reduce thermal distortion affecting optical properties of the laser. Concentric radially disposed barriers to heat flow that hinder heat flow in the radial direction may be added within the gain element to further reduce thermal distortion within the laser medium.
    • 一种固态激光介质,其包括与至少一个增益元件接触并且与至少一个增益元件串联交替的至少一个冷却元件,即冷却元件。 至少一个冷却元件和至少一个增益元件在具有中心点的界面处接合,其中界面在界面处被物理地修改,使得界面处的传热系数从界面的中心点径向减小。 修改的界面促进从增益元件沿轴向的热传递,以减少影响激光器的光学特性的热变形。 在径向方向上阻碍热流的同心径向设置的热流障碍物可以添加到增益元件内,以进一步减少激光介质内的热变形。
