Coherent electronic energy transfer and nonlinear polariton effects in anthracene-doped naphthalene crystals

“…Since that time, the field has developed tremendously and many review articles have been published on the subject of nonlinear optics and spectroscopy (96)(97)(98). Excellent books which have appeared on the subject include those by Butcher 99 After tunable dye lasers became available, many experimental groups began to collect two-photon absorption and excitation spectra of various organic molecular compounds, for example, benzene (112,113), naphthalene (113)(114)(115)(116)(117), biphenyl (1 Ma), anthracene (118,119), phenanthrene (120).fluorene (121), diphenylbutadiene (113). and acenaphthene (116).…”

“…The theory of two-photon absorption by polaritons is discussed by Boggett and Loudon (193). Experimental evidence of polaritons has been obtained by several groups using both linear (194)(195)(196)(197)(198)(199) and nonlinear (117,120,131,132,200) techniques. Polariton dispersion curves have been measured by many groups (131c,199,201-203).…”

“…Ovander and Petrenko(123),Meredith (124),Bloembergen (125) and others(126)(127)(128)(129). SHG spectra have been obtained for naphthalene(117,130,131), anthracene(130), and phenanthrene(120,132). Additional SHG studies include references(133)(134)(135)(136)(137)(138)(139), and other types of nonlinear effects which have been investigated theoretically and/or experimentallyinclude three-photon absorption (140), third harmonic generation (141), TPE with application to photochemical ( 142) and nonphotochemical hole burning (143), four-wave mixing (144-149), surface enchanced nonlinear effects (150-153), and nonlinear effects with optical waveguides (154-156).…”
