Pulsed cooperative backward emissions from non-degenerate atomic transitions in sodium
We study backward cooperative emissions from a dense sodium atomic vapor. Ultrashort pulses produced from a conventional amplified femtosecond laser system with an optical parametric amplifier are used to excite sodium atoms resonantly on the two-photon 3S $_{1/2}$ –4S $_{1/2}$ transition. Backward...
