Solid-state organic laser with a wavelength tuning range of 78 nm

We report the results of studies of the lasing characteristics of an organic solid-state tunable laser with a polymethylmethacrylate matrix doped with Chromene 3, Pyrromethene 567, and Pyrromethene 597 dyes. The features of lasing when using selective and nonselective cavities are described. Tuning of the laser wavelength with a spectral linewidth of 0.018 nm in the range 550–628 nm is obtained on three polymer laser-active media emitting in the yellow and red spectral regions.
