                                              SOLID STATE DYE LASERS



                         1.3.1  Introduction
                            Solid state lasers based on organic molecules as the active element have utilized a variety
                         of different host materials—plastics and polymers, organic and inorganic single crystals and
                         glasses, gelatins, and biological materials—and have been operated in a wavelength range
                         from 376 to 865 nm. One solid state dye laser has been offered commercially.

                            Data on the various types of solid state dye lasers are given in Tables 1.3.1 to 1.3.7
                         where the host material, dye, lasing wavelength, pump source and wavelength, and primary
                         references to laser action are tabulated. The lasing wavelength and output of  dye  lasers
                         depend  on  the  characteristics  of  the  optical  cavity,  the  dye  concentration,  the  optical
                                                                         1
                         pumping source and rate, and other operating conditions.  The original references should
                         therefore be consulted for this  information  and  its  effect  on  the  lasing  wavelength.The
                         references should also be consulted for details of the chemical composition and molecular
                         structure of the dyes and host compounds. 2
