CHEMICAL QUENCHING OF THE TRIPLET STATE IN FLASHLAMP-EXCITED LIQUID ORGANIC LASERS

Abstract

Greatly improved lasing of flashlamp‐excited organic dyes has been achieved by collisionally deexciting the triplet state of dye molecules with newly discovered chemical additives. Experimental results show the quantitative improvement of several principal organic lasing compounds when they are placed in solution with chemical additives. An explanation of the deexcitation mechanism is offered; the criteria for selecting proper chemical additives are listed.
