Optically pumped cascade radiation based on Na-Na collision energy transfer in Na vapor
Stimulated radiation based on Na-Na near-resonance collision energy transfer has been observed in the sodium vapor. The stimulated emissions from 4f or 4d level of atomic sodium are generated via two-photon resonant excitation of 4d level or dipole-forbidden two-photon resonant excitation of 4f level respectively and the related processes are discussed.
