Investigation of coherent emission in time-separated fields
L. S. Vasilenko, N. N. Rubtsova
Abstract:
An investigation was made of signals of coherent radiation generated by time-separated fields in an SF6 gas at moments t =T+nT (n =1,2,3,4) under the action of two pulses of standing-wave CO2 laser radiation. The amplitudes of such signals were investigated as a function of the detuning of the laser frequency relative to the center of the transition line of SF6, as a function of the amplitude of the exciting radiation, and also as as a function of T. The rates of relaxation of the polarization, γ12= (46 ± 5)×106 sec–1·Torr –1, and of the populations, γ = (42 ± 4)×106 sec–1·Torr –1, were found at pressures of 1–5 (mTorr). A comparison of γ12 and γ gave information on the nature of collisions in the SF6 gas.
