In this paper, we demonstrate the laser characterization of Cr:ZnS/Se polycrystalline gain media in non-selective unpolarized, linearly polarized, and twisted mode cavities. Lasers were based on post-growth diffusion-doped, commercially available ant

It was demonstrated that in the nonselective cavities, suppression of the spatial hole burning via "mode twisting" for lasers based on polycrystalline Cr:ZnS and Cr:ZnSe results in linewidth narrowing to ~80-90 pm from ~20-50 nm.
