热梯度诱导的应力双折射和退偏损耗以前报道的Yb：YAG平板中的平面应变近似。在本文中，我们提出了这些现象的分析应用一个完整的三维处理的沉积泵浦功率和冷却的Yb：YAG板。我们处理直线通过和曲折的传播和情况下的板长沿着晶体[1 1 1]和[1 1 0]轴。我们还描述了无掺杂的布鲁斯特端和泵浦边缘的平板中的损耗。
The thermal-gradient-induced stress birefringence and depolarization losses were reported previously for a Yb:YAG slab in which the plane-strain approximation applied. In this paper we present analyses of these phenomena applying a full three-dimensional treatment of deposited pump power and cooling in a Yb:YAG slab. We treat both straight-through and zigzag propagation and the cases of the slab length along the crystalline [1 1 1] and [1 1 0] axes. We also describe the losses in a slab with undoped Brewster ends and pump edges.
