✦ Synopsis

Using the second harmonic: ot';l mode-lucked Kd 3c I;lscr, WC StlOW lll~il 11X ellicicnt quenching of the St state in crystal violcr (r~ < IOe8 see, yet Q < Ill 4 in ethanol). involves very rapid repopulation of the ground sratc. The rcpopularion time exhibits a cube rout dcpcndcn~r: on solvent viscosity. We argue ttml our data arc best csplnined by dticct inrcrnal conversion. We suspcst that the chss OF triphcnyl and diphcnylmcthanc dyes should prove to bc clTicicnr and vcrsatilc blcachablc shutters and passive mode-locking clemunts I'or I;1scr consrruotion.
