Volkin, H C

A direct solar pumped laser operates on emission from the phosphorescent T1 -> SO transition of a suitable dye molecule used in liquid or solid solution. The first excited singlet electronic state s1 is excited from the ground state so by light from solar concentrators absorbed in the absorption bands of the strong spin-allowed transitions sp <- so, P > or = 1, where the primary absorption band is usually P 1. Excitation of dye molecules to the first triplet state t1 occurs via intersystem crossing from s1 to the triplet state manifold.
