Abstract:
1. An amplifying medium for solid-state dye lasers, comprising: an essentially solid active medium which comprises at least one type of activatable particle which can be excited to emit laser light in a certain wavelength range, optical feedback means which define a resonator for the laser light, where the feedback means comprise an essentially solid feedback medium which has a periodic structure, said feedback medium being made from a polymeric dispersion film having a crystalline structure, wherein said polymeric dispersion film comprises core/shell particles which can be formed into a film, said core/shell particles having a core material and a shell material which are able to form a two-phase system, where the shell material can be formed into a film, and the core material is essentially dimensionally stable under the conditions of film formation of the shell.
