Abstract: An ecologically perfect generator of singlet oxygen O₂ (a¹Δ_g) is proposed which fundamentally differs from existing singlet-oxygen generators. Excited O₂ (a¹Δ_g) molecules are generated due to interaction of the O₂ (X³Σ^-_g) molecules with a quasi-monochromatic field, which is supplied from an external source to a closed volume – an optical boiler containing oxygen. It is shown that, by pumping continuously the optical boiler by the light field of power ~3 × 10⁵ W, it is possible to accumulate up to 40% of singlet oxygen (O₂(b¹Σ⁺_g)) + (O₂ (a¹Δ_g)) in the boiler volume during ~10^-2 s.
