The kinetic dependences of transmission variation in porous glasses activated by various laser dyes (rhodamine 6G, coumarin 7, coumarin 30, oxazine 1, Nile blue B), on illumination by laser radiation with an energy density from 10/sup 18/ to 10/sup 21/ photons cm/sup /minus/2/ sec/sup /minus/1/ is studied. A technique is proposed for determining the quantum yield /gamma/ of photobleaching of the activated porous glasses from the dependences obtained in the work. The values of /gamma/ have been determined for the indicated compositions.
