Title:
AMPLIFYING MEDIUM FOR SOLID-STATE DYE LASERS
Document Type and Number:
WIPO Patent Application WO2003044911
Kind Code:
A3
Abstract:
The invention relates to an amplifying medium for solid-state dye lasers and a solid-state dye laser provided with said amplifying medium. Said amplifying medium comprises an essentially solid active medium, containing at least one sort of particles which can be activated and which can be stimulated to emit laser light of a particular wavelength and optical feedback means which define a resonator for the laser light. The feedback means comprises an essentially solid feedback medium which has a periodic structure. The amplifying medium is characterised in that the feedback medium is a polymeric dispersion film with a crystalline structure which particularly comprises core/shell particles which may be coated.
