Ring Structures in Radiation at the Output of Solid-State and Dye Lasers with an Intra-Cavity Diffuser

We observe transformations of radiation patterns with broadened rings at the output of Rh101 dye and Nd :YVO 4 lasers with Fabry–Perót (FP) cavities containing a cuvette diffuser with a mixture of LiF particles and isobutanol at changes in its state of immersion and in coherence of laser radiation....

Description
Summary:We observe transformations of radiation patterns with broadened rings at the output of Rh101 dye and Nd :YVO 4 lasers with Fabry–Perót (FP) cavities containing a cuvette diffuser with a mixture of LiF particles and isobutanol at changes in its state of immersion and in coherence of laser radiation. We compare the registered patterns with ring structures at the output of lasers with other sources of scattering in FP cavities. The mechanism of a low-coherence generation in a laser with an intra-cavity immersion diffuser is considered to explain the rearrangement of radiation patterns.
