Abstract
In this paper we present calculations of the effects on thermal lensing of bonding undoped host crystal to the ends and edges of edge-pumped slab lasers. Using ray tracing and finite element analysis we simulate the distribution of absorbed pump power, 3D temperature, stress, and surface displacements. We numerically calculate the induced lensing due to thermal and stress gradients, and deformation induced end effects. In slabs with undoped material bonded to the edges through which pump light enters, the induced lensing has an "m"-shaped profile while undoped Brewster ends reduce deformation induced lensing.
