Theoretical and experimental investigations compact slab guide resonators

Investigation of compact slab guide resonators with variable geometry, guide material and surface quality by automated scanning interferometer with high precision positioning system has been performed. Obtained optimization criteria are used to improve parameters of compact (including dimensions up to less then some cm) slab guide and multi pass laser resonators. On the other hand very high sensitivity to resonator surface quality and internal media properties allows to use such a structure as instrumentation for development of optical and fiber optical (chemical, biomedical etc.) sensors.
