Abstract
The light backscattered from a plasma produced by focusing a 1-GW Q-switched ruby laser has been measured. The reflection coefficient of the plasma is of the order of 1–2% and the reflected energy increases with the incident energy. The backscattered light is Doppler shifted; the shift is not uniform but varies markedly along the focal spot indicating a concave reflecting layer penetrating into the target with velocities of (2–4) ×106 cm/sec. The second harmonic of the ruby laser is also present in the backscattered light.This publication has 11 references indexed in Scilit:
