摘要：

Visible superfluorescence was observed on twenty lines of Eu I after two-photon excitation. The emission cascade 1961 nm (or 1926 nm), 605.7 nm is studied in detail. The yellow peak power varies as the square of the excitation number, N, pulse width and delay vary as N-1 in agreement with theory. When the emission overlaps with the excitation pulses, the ir emission is dominated by cooperative resonant Stokes radiation (Raman superradiance"). © 1979."
