It is demonstrated that excited singlet state absorption and stimulated emission or triplet state absorption can be utilized for spatial light modulation by organic molecules. A kinetic analysis shows that for some favorable cases the modulating laser intensity needed to achieve 45% modulation can be as low as 100 nW/μm2. The potential for spatial light modulation is discussed.
