Tunable organic solid state laser

The creation of spectrally narrow tunable wavelength over a wide range, having a small loss in laser generation power is an actual problem in modern laser physics. Lasing characteristics (FWHM) of solid state active media based on Chromen 3 (Ch-3) in polymethylmethacrylate (PMMA) are investigated. Patterns of changing the lasing characteristics depending on resonator’s geometric parameters. It is demonstrated that the wavelength of solid state active media in specific resonator's geometric parameters can be narrowed to the lowest value possible. Such laser properties are known for wide application in laser spectroscopy
